REFLECTOR:accidents/incidents

I saw the Burkut demonstrator do one at Oshkosh a few years back, wasn't
exactly a loop- more like and "egg" but  I was certainly impressed- I don't
plan on attempting the same in my V, but maybe a roll or 2 - just need to be
quick on the down elevator since there is not enough negative pitch to keep
the canard flying while inverted, because it would be trying to fly with
negative incidence, and you would end up making a really sloppy split S

At Copperstate 2003 I watched a Long-EZ do aerobatics - he never did a
complete loop.

There is an air show performer that does Aerobatics in a LongEZ., I've seen
him perform a couple times.

Does hammerheads, loops etc..

Geeee, I wonder how he survives doing that all year long, over and over
again?
