I use my spare time at work on full-flight military aircraft simulators to fly around and try things like taking off, landing, etc...it was loads of fun, and once you were competent at landing a functional aircraft, you could try doing it with any combination of aircraft faults. I'm fairly confident I could land a [fully functional] C-130 if my life depended on it. My new challenge is trying to hook up with a tanker, during which I've caused many a catastrophic accident.
