Not sure why they can't just set the altimeter to show zero on the ground and avoid all the MSL-AGL hooraw. As I recall, the altimeter has to be set to 29.92" above 18,000(?) feet and to the actual air pressure below that, but for the specific purpose of an airshow, setting it to show AGL seems worth a minor rewrite of the regs.

Do you remember when about 2-4 T-Birds pilots all crashed into the ground at Indian Springs during a practice session in the early 80's? I was there quite awhile after the crash and you could still see the black scar marks on the ground. Very sobering.
