I have watched that 3 hour 15 minute hearing - first question is who trained Sam Graves on AoA?
Second is who is willing to tell him he does not understand it in the slightest.
FAA should pull his licence or better still lets give him a few simulator tests.
Much of the hearing was professional - shame that the pilots were not.
Show of hands (not high and extremely brief - put them up and hold them up - it was a direction) and Sam Graves exclusion of all 737 time and only mentioning the MAX time experience of the pilots - is very poor and every professional pilot should bring this to congress attention.
And explain he has zero idea of AoA if he calls the AH one.
