A number of people on the plane were scared ... but it landed and the FBI took the men aside to investigate and question .. the men claimed they were musicians and were eventually let go
Basically it comes down to .. if they don't commit a crime .. they can't be held
Problem is .. by that time .. it may be too late
Thank you. :) If they weren't up to sumpin criminal then they were at the very least playing out an elaborate hoax. Yes, at those altitudes, it would be waaaay too late.
