Unless it was really, really strong C4, she wouldn't be able to get enough up there to cause an explosion that would blow up the whole plane, not that you'd have to do that to make it crash. I'm picturing it as a tampon-sized TNT stick that would explode me in two, leaving my upper torso alive long enough to utter "Wow, that was the best BLOW job I've ever done!" *dead*
