from Powerline. Please note the whole series of lies from the 'scholars', and that the testimony from everyone else demonstrates that they were deliberately acting to cause problems.
Leaves two possibilities, possibly connected. One is they just wanted lots of publicity of how 'poor muslims, even scholars, are mistreated'. The other is they wanted to make as much trouble as possible specifically to cause problems for flight crew and other passengers(the standard call the racist, bigots, etc.) so that when the real hijackers attack, people will hesitate to do something.
Either way, they're a bunch of dishonest canker sores on the ass of humanity.
