One of those time I really don’t agree with you. I doubt she walked directly under the wing towards the prop, she probably went wide to go around the wing but not wide enough and just caught the prop.
SHe just got off the plane, probably just had fun with a ton of family/friends, gets off the plane its dark and noisy, its an airport afterall and just gets caught off guard.
It really doesnt sound like just just walked straight into it.
