You went through all that trouble instead of just showing me a scan of a pilot's license? the aircraft in the first video is not pulling high G so no wonder the slats are quite gentle.
Since you asked, yes intro flights are probably much more expensive in the UK than in the US, if you want to fly with me in a Stearman it will cost about £360 per hour, I don't remember what we charge for the 152's or warriors but it's around £150 per hour.
Heres the vid of me and fruitbat in a Stearman taken from that GoPro camera on my head in my avatar pic, check 14:30 for the 'hello Crumpp' and 17:30 for some basic aero's.
