twist. an air force pilot at the top of his game dies in a stunning crash. and his fighter jet could be to blame because of what may be a fatal flaw. abc's brian ross investigates. >> reporter: it is the f-22, nicknamed the raptor. >> incredible capable. incredibly lethal. >> reporter: in the promotional videos, complete with music, the

manufacturer lockheed martin uses every trick in the book to make the f-22 look like $422 million well spent. >> i think it's going to change war fair completely. >> reporter: but the truth about the f-22 is much different. it's never been flown in a combat mission and it has a potentially fatal flaw in the oxygen system. captain jeff han yip was killed after he lost oxygen and his jet crashed in alaska. but the air force blamed him, not his $500 million aircraft. >> jeff was an awesome pilot. and an even better man. i am so proud to call him my brother. and he gave his life. he just deserves the truth.

>> reporter: this computer simulation prepared by the air force shows what happened to haney. >> the beeps going on tell something is wrong with the airplane. four seconds after that coming up on the screen, he is no longer gets oxygen in his mask and he is probably getting the feeling he is suffocating. >> reporter: he was conscious throughout the dive and failed to make the right moves, says the air force. but gannyard feels that is hard to please. is he close to making it? >> not close enough. >> reporter: the air force paid tribute with a fly over. the family is now suing the air force, saying that haney was not at fault, they want to protect

the reputation of the f-22. >> it feels like a number sometimes. the jets are worth a lot of money. >> reporter: the entire fleet of the f-22s were grounded for five months last year after 14 reports of pilots losing oxygen. but after the planes were put back in the air, the problem persists with 11 reports of oxygen problem. one pilot said that some pilots are asking not to fly the f-22 because of the safety issue. >> if i knew what the problem was, it would be good. i just haven't found the problem yet. >> reporter: the f-22 has had huge profits for the lockheed martin company. and today at the corporate headquarters, the final of the f-22s were turned over to the air force. >> it's an an improvement to the modization effort. >> reporter: but even if the

oxygen flaw is fixed, the plane is still a waste of taxpayer dollar. >> it's not flown a combat mission in afghanistan or iraq or are they planning to do so. >> reporter: senator john mccain said the plane was designed to fight a soviet jet that was never built and has no use now against the enemies that they are fighting. >> there is no purpose, unless you believe that al qaeda is going to have a fleet of aircraft. >> reporter: its critics say the air force can't even give the pilots enough hours in the air to train them. >> it's in the shop all the time. they are lucky if they can fly it every day. >> reporter: is it badly designed or badly produced in.

>> both. >> reporter: for now, the f-22, the future of the america jet fighter jet s a $500 million aircraft some pilots are asking not to fly. what are they going with the planes? >> there are a lot of air shows around the country that could appreciate fly byes. >> reporter: and senator mccain wasn't joking. that is just where we found the f-22s, performing tricks in air shoi v shows across the country. a very expensive stunt plane. the air force says of the f-22s have been deployed to the middle east and it tries to figure out what is wrong with the oxygen. cynthia. >> thanks to you, brian. up next, i will show you how i got ready for my close-up into
