What to do if the canopy opens during flight ?

Hi,
In the video at www.fulldeflection.com , Kirby Chambliss has his
canopy fly open during flight.
He was very cool about it. I think he made all the right choices.

I've had a door open a few times during flight too, on a Cessna 152.
My instructor showed me how to close it in-flight.

You slow down to nearly stall speed, which means you can open the door
just wide enough to slam it well enough to close. Although it would be
safe to leave open.

Imagine if Svetlana Kapanina, or Patty Wagstaff had their canopies
open. There'd be hair everywhere.

Superdoof.
