derby against rangers, which will mean they will be crowned champions of the scottish premiership for a seventh season in a row. with a 15 minutes left at celtic park they are leading 5—0. odsonne edouard with a couple of goals for brendan rodgers‘ side. not sure how rangers manager—in—waiting steven gerrard will be feeling. bbc scotland understands rangers are confident gerrard will take over in the next few days, with talks between the club and the former liverpool and england captain said to have gone well. it's another big day in the premier league, as champions manchester city travel to west ham with a record points haul in their sights. pep guardiola's side are currently on 90, and with four games left to play, chelsea's record total of 95 is well within their reach. as for west ham, they're not yet safe from relegation. steve wilson is at the london stadium for match of the day two. ‘sand

‘s and every person listed football fan, most football fans are pessimistic will be able to work out a scenario where west ham go down. i think they will be ok, but i think the two manchester clubs are yet to play, they will not feel comfortable until they can get one more point, certainly three on the board. in today's other match, arsene wenger travels to old trafford to take on manchester united for the last time as arsenal manager. full commentary of that one on bbc radio 5 live from half past four. chris coleman has been released from his contract as sunderland manager. coleman joined the club last november, but was unable to stop them going down to league one — a second successive relegation. owner ellis short has also confirmed he has agreed a deal to sell the club to an "international consortium of football investors". it's led by the eastleigh chairman stewart donald and will take over sunderland subject to efl approval. manchester city play lyon in the second leg of their women's champions league semi—final this afternoon. it's 0—0 on aggregate,

largely thanks to this save from city's karen bardsley in the first leg. kick—off at 1:45. chelsea also play at four o'clock this afternoon, but they have it all to do against wolfsburg, having lost the first leg 3—1. day nine of the world snooker championship is underway. judd trump has been in second—round action. he was trailing 3—1, but came back to wind the final frame of the session to level at 4—4. on the other table there was a superb session from another former finalist — dingjunhui. he won all eight frames against anthony mcgill. it's best of 25 frames for a place in the quarterfinals, and both matches resume tonight at 7 o'clock. that's all the sport for now. now on bbc news, it's time for the travel show. this week on the travel show, we help celebrate 90 years

of australia's legendary flying doctors service. what a remarkable bit of kit! yes. we investigate the mysterious ghost lights spotted over a town in texas. and we head to china to try out a style of skiing which is reckoned to be over 8000 years old. this week i'm in australia's northern territory. this massive state covers nearly 1.5 million square kilometres. it is the most sparsely populated part of australia and living out here can be hard. because of the sheer size of this part of the country, air travel has been an important part of life in the northern territory for the past 100 years. it's also the reason that the royal flying doctor service was set up 90 years ago, pioneering the then—revolutionary idea of using planes to bring medical care to remote communities. i have come to their central operation based

in alice springs airport. from here, the service dispatches emergency response planes all over the northern territory, and it is a busy place. as we arrived we saw one of the planes bringing in patients from the outback. one of the planes has just arrived. two patients were taken off, whisked away to hospital. it is a perfect opportunity to see what's on—board, as one of the senior flight nurses, cathy, is waiting for me. the service's fleet of planes are packed with cutting—edge medical equipment ready for any emergency. hello. hi! how are you? good, thanks, henry. what a remarkable bit of kit you've got here. yeah. explain what you have here? we have a miniature intensive care unit, really. we have monitoring, we have drugs on board, we have anything to do with what you would see an intensive care unit.

we can take anything from a sore toe to a fully intubated patient who has probably had some trauma or cardiac arrest or something like that. how many square kilometres do you cover out of this base in particular? just over a million square kilometres, which is about four or five times larger than great britain. that's a lot of ground to cover. how essential would you say the royal flying doctor service is to the people of the outback? extremely important. it's their lifeline. if they had to come by road, it would be up to eight hours by road, and the roads are not always that good. there are camels and donkeys and potholes and water. as opposed to probably up to a one—hour flight. so they get into definitive care much quicker. but the high—tech standards we see today didn'tjust happen overnight. in 1917 founder reverend john flynn first had the idea of creating

a flying doctor service, but it took him another ten years to turn his plans into a reality. the first planes took to the skies in 1928. those first planes were very basic boneshakers by today's modern standards, but slowly innovations like pedal—powered radio were introduced, helping to build a lifeline between the flying doctors and the remote communities they served. newsreel: this time the doctor is landing on a regular periodic visit. the sisters are waiting as it lands, welcoming former raaf pilot robert chadwick and dr miller. news of the success of those early pioneers quickly spread, and eventually the service became a national network across australia. in 1955, queen elizabeth visited from the uk to officially bestow the service with its royal title. today, as modern planes and medicines save even more lives, the story of the flying doctors

continues to capture the public‘s imagination around the world. tourism is a crucialform of income for the service. here at the flying doctor tourism facility, visitors can learn how the service works and what flying was like back in the day. 90 years of history are brought to life with some of the objects that made it all possible. even the building itself is historic. this building behind us was the original building in alice springs. this is where we ran our head office and also our communications department. so it's a listed heritage building, and it's now a tourist facility and cafe. as well as educating tourists about the service, the facility and shop are a crucial source of income. so how important is tourism to funding services like the royal flying doctor service? tourism is extremely important. 100% of our profits

from the tourist facility go back into the royal flying doctor service. it helps fund the purchasing and also the medical equipping of our craft. we have 25% of our funding as a gap which needs to be filled and that is where our money comes from. over the decades, the flying doctor service has saved countless lives. it's amazing to think that it's thanks to a small—town church minister who wanted to do his bit to help people living out in the bush. something tells me he would be very proud of the people who still fly to save lives today. we have gone from just a few planes to 67 aircraft, from 2a different locations in and around australia. next up, we leave the australian outback behind and head to america,

where for over a century people have reported seeing strange lights on the horizon in the texan town of marfa. no—one is exactly sure what they are, but many people claim to have seen them, so we went to meet them. this is the rambling boy, broadcasting live from the radio studios in downtown marfa, texas. i want to say a few words about marfa. it's a very small town, 2000 people. it was a cattle town and a ranching town for many, many years. we have become an international arts centre. but we are still a small texas town and it's an interesting combination. i have never seen the marfa lights.

i have been told that the best time to see them is in the winter. a couple of hours after sundown, or a couple of hours before sunrise. a couple of hours after sundown in the winter is my suppertime. and a couple of hours before sunrise is my sleeping time. and besides that, it's cold out there in the viewing station in wintertime. but i believe they are there. at least, i believe something is there. because i know a lot of reliable people who have seen some sort of light out there. scoffers will tell you that the marfa lights are the lights of automobiles travelling north from presidio on highway 67, or the lights of aeroplanes, or ranchers on mitchell flats, or a border patrol helicopter. many people who think

they are seeing the marfa lights are undoubtedly looking at automobile headlights or ranch lights. but it is clear that there were other lights out there before there were either automobiles or electricity, and they are still out there. i grew up in marfa. i was born in 1950. so i've been around, i have seen the lights and i've heard about them all my life. we show the lights regularly to people from our ranch. today we're in front of the viewing centre which is on the road between marfa and alpine. it does cause some confusion because of the way it's pointed. the orientation points

you to where it's easy to be misled by automobile lights, which are coming up from presidio and ojinaga. not very many people know that from right here, there is a mesquite tree right there, and if you stand about ten yards from the mesquite tree and look straight ahead, there's a bush, there's another green bush, and you'lljust see a line, if you really look, of little green bushes that form a line out to a tree, and that tree is about a mile and a half away. right over the tree is where the lights are.

i don't remember a single time that someone didn't say, have you seen the marfa lights? so now when people ask if i've seen the lights, i say, have you seen the lights? and most of them haven't. but the ones that have, they are the ones who are really interested in knowing what the lights are. i came here about three years ago, to marfa, and immediately fell for the landscape. i was stalking the lights every night. i think maybe i saw something like them what i wasn't paying attention. i do try very hard to find them. i'm neverquite sure. i got this poem, which is called western poem. "purple clouds, my doubts. iridescent cream, my loss. amber street light, my reading. my appetite, my appetite. red striped sky, my confusion.

bright yellow, grey sky, my otter. car lights, my commotion, telephone poll, my wishes. stop sign, my fear. black cloud, white sky, bliss. blinking signals, my intentions. black mountains, too many suggestions. skipping white lines, my attention. a young cowboy first saw the lights. the horns on your van, my defensiveness. that old train, my dreams. that old train." still to come on the travel show... the incredible journey of one woman who has a passion for wild swimming. water is my domain. i'm happiest in the water. and we learn to ski the traditional chinese way. so, stay with us for that. next up, we continue our series

looking at incredible journeys happening around the world, as we visit snowdonia national park in wales. it's here where one woman's passion for swimming has led her to exploring this wild and unique landscape in a completely different way. it feels pure. i don't think i feel anything more pure than swimming in a mountain lake. the water is my domain. i am happiest in there. over the last few years i have been exploring snowdonia national park, by wild swimming its 250 lakes. i have swum about 150 now.

i am always searching for somewhere for a quick swim. if i can squeeze in a new lake then i will always go for that. snowdonia national park is a mountain range in north wales. it is a beautiful area to live in. the mountains here feel very rugged. much more tightly packed. and in between that is where you get the lakes, and although they may be much smaller and a bit of a trek to get to, i don't know, for me, it makes it a little bit more special. i've always swum since childhood, my mum was a swimmer.

my mum passed away 11 years ago and i found grieving was very hard for me, so i think the time alone was part of it. i do obsessively swim now and i did not before, but i did not make a conscious decision to start swimming this way, it was definitely subconscious. i always have this, i call it a nervous anticipation in the tummy, but the nerves can be intimidation because sometimes the water is dark, you don't know what is inside, beasties or weeds, but that's all part of it for me, is wanting to feel those nerves. i am not somebody who

wants to dive down. sometimes i just want to be submerged up to my shoulders and just feel that feeling of the cool freshness on my skin and, yeah, sometimes that is just enough for me. it is a time to leave everything behind and that's a huge part for me. documenting the lakes visually came about by being scared of what was underneath the surface. and i would take a camera

under the water with me to capture what was — what was in there, and i would rush home to have a look, to see what i had captured, and discover that there was nothing, i never saw anything, but occasionally, i would get a glimpse of myself on the camera or other people i was swimming with, and there was a graceful beauty in seeing people underwater. you are seeing the landscape for a totally different reason. most people are coming here to go walking or to hike to the top of mount snowdon or whatever. because i'm doing this, i have seen parts of snowdonia i would never have seen before. i have no desire to go to the top of anything any more, i — yeah, there is still so much to discover. vivian rickman—poole wild swimming in wales, and we will have more incredible

journeys for you soon. to finish up though, we are off to china, which strangely for some has been described as the birthplace of skiing ever since cave paintings of skiers were discovered in the country's altay prefecture. we went to learn more. i'm afraid that is all the time we have this week, but coming up next week... if your invite was lost in the post like mine, ade visits windsor to find ways to experience britain's upcoming royal wedding without heading to the church on the big day. don't forget, you can follow us wherever you are in the world byjoining our social media feeds. all the details are on your screen right now. but from me, henry golding, and all the team here in alice springs, goodbye. good afternoon. some wet and windy

weather on the way for south—east england and parts of east anglia where we could see lots of rain in 24 where we could see lots of rain in 2a hours. the rain and wet and windy weather is associated with this cloud friendly across france and working its way north. away from that, there has been dry and bright weather, particularly further north and west. do the rest of today, for the north, some good spells of sunshine, one or two showers and the brightness feeding into wales and south—west england. more cloud for central and eastern parts of england. temperatures hear a bit

disappointing. we will see the wind strength and, a high of around 13 degrees. as we go to the evening, the area of low pressure approaches from the south, bringing heavy rain and strong wind. as we move through the night and into tomorrow, some localised flooding possible and some disruption possible to travel as the rain makes its way into south—east england and east anglia. through this evening and overnight, the rain starting to work in, looking at gailes on the coast. away from that, it will be dry with clear spells, the showers dying out and clearer skies, seeing temperatures dropping below freezing in some spots. although it will be eight shall you start, we will see the best of the dry weather there over in the south and east, four east anglia, this is what it is looking like tomorrow morning, lots of heavy rain and strong winds, gusts up to 50 mph and

it is going to edges way north and west as we move through the day. away from that, it we will see more in the way of dry and bright weather, temperatures at around a max of 1a weather, temperatures at around a max 01:14 degrees, but where we have the wet and windy weather, we will really struggle. as we go through and monday overnight tuesday, we will see the way in clearing towards the east, said becoming drier and brighter as we move through the day on tuesday, good spells of sunshine, a greatly improved day for eastern of england on tuesday. turning wetter in the west for northern ireland, parts of scotland, temperatures recovering on the high, tomorrow a maximum of 1a. taking oxford as an example for the rest of the week, we will see the temperatures creep up. this is bbc news.
