Interested,
give it a rest now, please. The girl did well. The label 'hero' came from the people whose lives she saved, and they are both entitled to their own opinion and not here to defend afforementioned opinion. You are the only one on the thread getting so wound up over what your personal definition of a hero is, and all it is doing is adding a sour note to a congratulatory thread.
While you, your friends and acqaintances are obviously made of something else, the professional pilots here (I note you give your job as author) acknowledge what a difficult thing this student pilot did, and I would like to add my own 'well done'. The step from Cessna 152 to a more complex aircraft is NOT easy, and to do it in those circumstances must have been scary too.
