Zoom Climb

Each aircraft was loaded with 10 minutes worth of fuel and an air start at various altitudes was used. The aircraft were allowed to accelerate to 100mph and were then smoothly pulled up into the vertical until they stalled out and toppled over. The altitude at the top of this zoom climb was recorded.
