One I was told about by the builder in W Australia.....He taxied out with his side mounted canopy int the part latched position to get some airflow thru the cockpit. Forgot about it till he took off, and became aware of it by the extra noise. Tried to close it but the lift generated by the canopy (1/3 total lift I was told)tore it out of his grip and smashed it against the starboard stub wing. Stalled in- I saw the results -broke main spar -extra foam in his seat saved him. Brave soul built another............is he still around Phil?
