I think aero's are an important part of eveyones training!!!! If you havent seen it before, how are you going to gain control if it happens unexpectedly. Maybe not in the first lesson!!!! Many people are freeked out when things dont go to plan, this is why we train for such events.
Dont be frightend about flying, more people are killed driving to the airport than flying.
If you truely want to be a pilot then go for it, I guarantee you wont look back!!!!!!
