My husband and his brother did this tour a few years ago and really enjoyed it. It think it was Tuesday and Thursday. Alas, the last time I checked (a few months ago) it had been suspended; pity because he was hoping to do the tour again next week.
Okay, maybe not crash is the word.... Intense, might be more appropriate.
One of the things you can do for instuments, is "Flying Blind" where you can only see the instuments, the instuctor totally throws off your sense of up and down, (Spins, Rolls, maybe a dive), and then you get control of it back, and have to straighten things out.
