BF 109 canopy and bailing out

[JG26_EZ]

A buddy's dad flew with the allies (P40's I think) back in the war, not in a 109, but I imagine alot of pilots in different planes doing the same thing...
He said that when ejecting, they'd roll over and use a foot on the stick to cause the plane to dip (upside down) and give them the final "kick" out of the plane they needed. Of course I'm sure every scenario is not the same.
