I went to an airshow on Sunday... It is a small place where people get close to the action (within regulations) and one of the performances was a Control Line Combat demonstration. Clearly the spectators thought it was impressive. Most of them had probably never heard about C/L.
I thought the next bit was even better: during a break in the main airshow, the Announcers accepted the challenge and got to fly too. I'm not sure what sort of a handle setup they had, as there was a skilled flier there who got the Combat planes flying first. The lady announcer did fine, the guy got a bit too adventurous and nosed in the airplane...
