The distinction between general and specific intent can basically be distilled down to "did I intend to intimidate this particular person in this particular way to cause interference." Vs. " did I do something I knew or should have known would cause a person to be intimidated and it did in fact cause interference. "First, I freely acknowledge that I have my butt in the wind trying to interpret case law and quote same to an actual lawyer, but I did find this. Does this speak to the concerns you had about specific vs general intent?

The distinction in this case really only means that you don't have to prove that you meant to intimidate this particular crewmember in this particular way but rather that you intended to do something that would cause a reasonable person to be intimidated under those circumstances. They then don't have to prove that you intended to cause the interference they only have to prove that it happened.
Where the rubber meets the road, if the government can prove that you intended to intimidate or assault, and they can prove that it caused interference; They don't have to prove that you intended to cause the interference. The government is only required to prove intent as regards intimidation or assault, they only have to prove that the interference happened not that you meant for it to happen.
Either way, as the head notes I posted above point out, the interference has to be caused by the intimidation or assault. That is where you were misreading the statute. Look again at the headnote for Eid.
49 USCS § 46504 is violated only if interference with flight crew members and attendants is accomplished by assaulting or intimidating flight crew member or flight attendant; viewing plaintiff passengers' version of facts, they did absolutely nothing that anyone could reasonably have believed was criminal--none of passengers made threats or got physical with flight attendants--and captain of airplane had no ground to believe that § 46504 was violated, even accepting everything flight attendants told him; jury could have concluded that captain acted unreasonably in diverting plane, forcing plaintiffs to disembark, turning them over to authorities and then refusing to let them re-board flight after police had cleared them.
