Sequence in my RV-3B: Canopy opened 90 degrees, held by strap, then strap broke and opened 180 degrees and rested on right wing. I remembered "fly the airplane" and added throttle to safely make it around the pattern and land. It's very possible that had I been a cooler pilot and only used enough power to climb and fly the pattern near minimum required airspeed, the canopy would have stayed attached. It only tore off when adding full power and getting above maybe 100 mph.
