I've wondered, how about ejecting the canopy? It must
be an effective airbrake, lots of drag, right?''

And then if you have to bail, that's one less thing
to do, which is good...

I'm not saying this is realistic. I would be surprised
to find a pilot who would do this even if it would
save his life. Holding a spin all the way through
the lenticular is probably safer too, but it isn't
realistic to think anyone could actually accomplish
such a feat of willpower.

But both are worth a looksie from the armchair...

I have always done this with the brakes out. It's

than I could.

I have yet to try the 'hold a magnetic compass heading

GPS
heading' method to compare. The latter two are difficult
to
practice realistically in a single seat aircraft without
being contaminated/influenced by the visual horizon.
