north of chicago, led to an inferno. >> one of the first things that our guys did, and they did a great job with, is assessing it, knowing it's bigger than us. then they're going to take care of victims on the scene, and then they'll work on the extinguishment process. >> reporter: more than 100 firefighters rushed to the scene, which only got worse when other products at the chemical plant started to catch fire. the facility that exploded, which operates around the clock, is one of several buildings that serve as the company's corporate headquarters and manufacturing site, where silicone is made. the disaster left the plant in ruins, which has made the search for those missing, for now, nearly impossible. because that building is so structurally unsafe, emergency responders have actually been forced to stop their search-and- recovery mission, possibly for days, until they can bring in heavier equipment. reena. >> ninan: kenneth craig. thanks, kenneth. well, now to florida, where investigators today retrieved the data flight recorder from a charter jetliner that slid off a

runway and into a river. the 737 was landing last night at the u.s. naval station at jacksonville, coming in from guantanamo bay, cuba. all 143 people on board survived, but some were hurt. mark strassmann is there. >> reporter: here it is, the boeing 737 military charter, standing in the shallow waters of the st. john's river, while a team of 16 n.t.s.b. investigators get a handle on what went wrong. >> we've got some challenges here because the aircraft, the bottom half of the fuselage, is covered with water. so we aren't able to get to all of the things that we need to get to. >> reporter: 143 people aboard flew through thunder and lightning on a return trip from cuba. passengers reported the plane bounced once while landing, then bounced again, before skidding from the runway to the river. you can see treadmarks in the grass leading to the water's edge. many people stood on the wings waiting for first responders and

rafts. >> our immediate focus was getting the people to safety. when i arrived on scene, most of the passengers had been taken off the airplane. >> reporter: the plane was full of service members and private contractors who work at the u.s. naval station at guantanamo bay, cuba. no one aboard was critically hurt. 22 people went to the hospital for treatment. so were the people in, like, pretty good spirits, pretty good shape, or were they kind of rattled? >> they were tired. they were wet. they wanted to just get into bed and get a change of clothes. but they were all, you know, very, you know, respectful and cooperative, and they were patient with us. >> reporter: so was the issue weather-related, something mechanical, or pilot error? maybe some combination. all areas of inquiry now for these federal investigators. reena. >> ninan: thank you, mark. north korea captured the world's attention today, firing off a volley of short-range missesoff. it was the regime's first test in more than a year. at the white house, the president signaled he still has

confidence in leader kim jong- un, tweeting, "i am with him." elizabeth palmer is tracking, in tokyo, the developments. >> reporter: the so-called projectiles fired from north korea's east coast splashed down between 40 and 125 miles offshore. the pentagon and arms experts are now studying satellite data to pinpoint exactly what these weapons were, but they are certainly not long-range ballistic missiles that could threaten the united states. today's launch is undoubtedly a message, but addressed to whom? north korea's leader, kim jong- un, may be signaling his frustration with the u.s. over the stalled negotiations to swap sanctions relief for denuclearization. talks between presidents trump and kim ended in a stalemate last february. the launch may also be a message to south korea, which has been taking part in joint military exercises with the u.s. air force.

north korea has always viewed such exercises as preparations for an invasion. the north koreans fired their weapons in the direction of japan, though they fell well short. but japan's foreign minister spoke with secretary of state mike pompeo today to tell him that his country's national security was not at risk. however, every government in this region will be watching anxiously in case today's launch is just a prelude to even more dangerous provocations by pyongyang. the white house did respond to the launch with a brief statement, saying only that it was aware of north korea's actions, and it would continue to monitor as necessary. elizabeth palmer, cbs news, tokyo. >> ninan: rising tensions in the middle east today. palestinian militants in gaza launched about 200 rockets into southern israel, testing an

already-fragile cease-fire. at least four israelis were hurt. israel retaliated with air strikes and tank fire into gaza. at least four palestinians were killed, including a pregnant woman and her young daughter. venezuelan's opposition leader today called for new demonstrations to force out president nicolas maduro. juan guaido also urged the country's armed forces to rise up and support his cause. adriana diaz is in caracas. >> reporter: their faces were concealed, but they wanted their presence seen. dozens of self-proclaimed president juan guaido supporters displayed a united front. they gathered at this plaza in eastern caracas... ( cheers ) ...the opposition's home base. the rest of the city was mostly quiet, despite guaido's call for morning rallies outside military installations in homes of attracting soldiers to his movement. we found lackluster protests,

like this one near the national guard base. we asked if their movement had lost steam. she said, not at all. they had more energy than ever. venezuela's dueling presidents are in a tug-of-war over the country's most-critical constituency, the military. ( speaking spanish ) on tuesday, guaido appeared with sympathetic soldiers, announcing a military uprising, which never materialized. instead, armored vehicles squashed opposition protests. since then, nicolas maduro has showed off his military support almost daily in photo-ops, including today, when he told troops he trusts their loyalty. yon goicoechea is part of the opposition's transitional government. so why would they appear next to maduro? >> well, they are-- they are afraid. they know that they can be tortured. that happens in every dictatorsh that happens until the last day. but we just need one lucky day. >> reporter: nicolas maduro has not issued an arrest order for juan guaido. guaido's team tells us that's because an arrest could spark

public outrage and potential u.s. military intervention, two things they say maduro does not want. reena. >> ninan: adriana diaz in caracas. thank you, adriana. and there will be more on the unrest in venezuela, as well as north korea's latest rocket test tomorrow on "face the nation." secretary of state mike pompeo will be among margaret brennan's guests. severe weather has killed at least nine people from the midwest to the south. overflowing rivers are drowning parts of texas. people in austin are being urged to stay away from flooded creeks. in davenport, iowa, the mississippi river rose to levels not seen there in more than 150 years. parts of the city's downtown remain under water days after a temporary levee gave way. about a dozen states could see moderate or major flooding along parts of the mississippi throughout the weekend. it's been one year since one of hawaii's largest and most- destructive volcanic eruptions. euullypewed lava for months, forever changing the

landscape of the big island. carter evans went there to see what's changed. >> reporter: when red-hot lava first exploded from the kilaeua volcano last may, it ripped over parts of leilani estates. large lava-filled cracks called fissures tore apart streets and blasted out molten rock. as the summer wore on, fissure number 8 produced a spectacular show, and we were there to witness the lava fountain. this is the most active fissure right now. we've been watching this one go for days. at times, it's been blasting lava up to 250 feet in the air. and this is what it looks like now-- a massive cinder cone surrounded by miles of black. scientists say the volcano produced more than a billion cubic yards of lava. that's enough to fill up more than 320,000 olympic-size swimming pools. >> it's still "wow." it doesn't matter how many times you've seen it. >> reporter: this eruption was in heath dalton's backyard.

his home burned down, and the massive fissure, now cooled, is all that's left on his property. do you think you'll move back into leilani, ever? >> leilani, possibly. our property here, no. it's not a possibility. we couldn't rebuild there. >> reporter: in all, more than 700 homes were destroyed. the river of lava left a canyon- sized scar on its way to the ocean. when it was all over, there were nearly 900 acres of new land. with all the destruction here, there is some beauty. this used to be a small bay, and now it's a brand-new black-sand beach. at kilaeua's summit, the changes are even more dramatic. >> what we have left is a massive new halema'uma'u crater, so, it went from about a half- mile wide to a mile and a half wide, from 280 feet deep to 1,600 feet deep. >> reporter: during the eruption, more than 60,000 earthquakes rocked the island, and the volcano spewed deadly sulfur dioxide into the air. geologists like janet babb are now waiting to see what's next.

you think we'll see lava again? >> yes, definitely, yeah. without a doubt, kilaeua volcano will erupt again. we just don't know when or where. >> reporter: carter evans, cbs news, hawaii. >> ninan: coming up, was a former tv producer and windsurfing champion wrongly convicted of murder?
