. >> again, jay rollins on the phone with me now, jay rollins, a former pilot with american airlines. and, jay, again, as we take a look -- again, this is probably the highest vantage point we've had today. runway 28 l. you can see the skid marks. earlier, we saw what appeared to be, again, the wing of the -- excuse me, the tail of that plane that had been clipped off. >> yeah. >> we heard from an eyewitness earlier that she saw the actual tail clip the seawall there as it approached the runway. jay, have you ever heard or seen anything like that, a plane as it's approaching somehow, some way, shape, form, or fashion, lose its tail? >> well, anytime you have an aircraft that comes in for a landing on speed, the tail will be down slightly anyway. the nose it up. and if you land short, in this instance, i believe i heard one of the eyewitnesses report that it looked like the nose came up briefly and then the slam down flat onto the runway. that suggests to me that at the last minute, the pilot may have realized he was too low, tried to pull the nose up at the last, and that only drove t

good point you make there, jay rollins, for joining me with your insight. we're going to hear more from the witnesses from the crash landing in this hour coming up in about 20 minutes or so. >>> in sanford, florida, tomorrow, day two of testimony of second-degree charges on george zimmerman. they heard similar testimony from the mothers frof trayvon martin and george zimmerman. martin's mother testifying for the prosecution and then just a short while later zimmerman's mother testifying for the defense. >> you heard screaming or yelling. do you recognize that? >> yes. >> and who do you recognize that to be? >> trayvon benjamin martin. >> do you know whose voice that was screaming in the background? >> yes, sir. >> whose voice was that? >> my son george. >> george zimmerman has pleaded not guilty to the shooting death of trayvon martin. he claims self-defense. so no experts being allowed to weigh in with their testimony on exactly who that voice is on the 911 tape. so how does this affect the jury? >> the jury is left to its own devices to decide which mothe

. >> reporter: jay rollins is a retired american airlines pilot and flight instructor in south florida. he says that reports of asiana's slight -- flight records go arounds are six to eight times higher. >> if you have been in the simulators, practicing year after year doing instrument approaches, where everything is set at a, act way to do it. and then you're thrust into an environment where you have to do a visual approach that you don't do regularly, you'll make errors. >> reporter: we're not saying that that's what happened. that fatal crash is under investigation. still, the gps simulator is a great tool to use when teaching pilots how to fly. i also learned today that some pilots believe using gps for landing could become universal. reporting live in hayward, nbc bay area news. >> as you well know, the asiana air crass triggered widespread delays. and it seems an employee is now accused of taking advantage of the situation. a 44 year old and his wife stole luggage from passengers who were supposed to fly into sfo but couldn't. surveillance cameras caught it on tape. they say valu

joining me now is jay rollins. thanks for being with me, jay. >> good morning, betty. >> asiana representatives refuse to blame pilot error. the associated press says this. the association indicates that the pilots fail to realize until too late that the aircraft was too low and flying too low. nothing disclosed by the national transportation safety board indicators reports any problems with the computers or automated systems. jay, from what we know so far, does it appear to you that pilot error had a role in this accident? and well, sadly, i do believe that pilot error is shaping up to be the very cause of this. we know a lot about the what and the how, now we have to determine the why. these pilots, you had a captain in the left seat who had plenty of hours flying, but he was new to this aircraft. then in the right seat, they had instead of a regular first officer, they had an instructor/captain in order to instruct the first pilot. that pilot was well qualified on the aircraft, but he was new as an instructor. s

we want to bring in retired american airlines captain jay rollins. he joins us now from miami. jay, hoping you were able to hear the latest from deborah. in terms of what you've seen, read and heard about this accident, are there any plus automobi plausible conclusions that come to mind? >> what strikes me, the first time she mentioned their target speed was 137 and they let the aircraft to slow well below that speed such that the stick shaker would begin, that tells me that the aircraft was approaching stall. what it sounds like to me happened was they were indeed high and fast. pulled the throttles all the way back to idle in order to get the aircraft in position for landing. what is not normal is after they got the gear and the flaps down, which is a high drag situation, with the power all the way back, the aircraft will slow very quickly once they get to the glide path. and a pilot has to be very conscious of that and leave the power as the speed slows and approaches the target speed. if you don't, it will shoot right through it and before you know it, you're getting a stic
