grady trimble is live at reagan national airport in arlington, virginia. >> reporter: and, jon, there are records that staffing levels of air a traffic control canners here at reagan at the time of the crash were not normal, that one person was communicating between planes and helicopters when normally those jobs are done by two separate people. as you noted, investigators have recovered the black box from the black hawk helicopter. that will be critical in their investigation because if, in fact, the helicopter was flying too high as has been reported and as president trump has stated, then the black box would reveal that to investigators. you can see the debris in the potomac river there as the ntsb has begun removing it from the river. it's bringing in barges that have not yet arrived as far as we can see to help with that process. the agency has also started interviewing the air traffic controllers who were working at the time of the crash. they'll look into their training as well as their hiring. >> what i can say is in this incident it should not hav

grady trimble live with more. hi, grady. >> reporter: hey, griff. and the black box from the helicopter in particular will be critical in this investigation because if that helicopter was, in fact, flying higher than it should have been, the investigators will be able to use that black box the tell. to tell the. >> the black hawk was too high. it was above the 200 limit by double. it shouldn't have been there. and there were some other mistakes made too, and i pointed them also, and i was right on all of them. they'll still do an investigation just to check it out. >> reporter: the ntsb is not responding to president trump's comments that dei hiring of air traffic controllers during the biden administration played a role in the crash, but it does tell us it's interviewing the air traffic controllers who were working at the time of wednesday's mid-air collision. >> we'll go back and looked at their past probably 72 hours, even 2-3 weeksful we'll look at their training, their hiring, everything. what they probably ate that day. but it is not one point

going to ask a question i believe grady trimble tried to ask at the end, why?ould there be a discrepancy like that? is there a problem with the radar scope question is you were chatting you said it's probably the most accurate. said this plane was probably a threaded toy 5 feet when the crash happened. why, why? because i think it was it three to 25 feet. i honestly think he misspoke when he said radar showed the plane at 200 feet. i think he meant to say that helicopter showed at 200 feet. because that is where the helicopter was supposed to be there a look at the track of the helicopter it was at 200 feet not long for just a few seconds before the collision. i think the helicopter made a relatively sudden climb maybe they were not aware of it. it was a gusty night sometimes when gusts can lift you up and down but i think that's what the discrepancy is i think he was referring to the chopper at 200 feet which was where it was expected to be. the plane at three to 25 feet. there is virtually no question in my mind the plane was exactly where it was supposed to
