"7. If a ground imperfection pitches you up into a high alpha on take-off or after landing and while slow...be the best pilot you can possibly be. This is gonna be tough. Finesse on the controls will possibly save you. Application of full power certainly won't save you."
Maybe my crash is instructional... https://youtu.be/l22ftmf2qK8
The jet had enough weight in the tail to move the CG back ~15mm aft of the factory marks. Wind was dead calm so no additional airspeed over the controls. The jet veered left and was headed toward tall grass causing me to jerk full up elevator in an effort to get off the ground fast. The nosewheel hit a bump causing the nose to be pitched up. After the resulting pitch up I kept full power until the jet reached a peak of about 20 feet. Nothing I did with the controls had any effect. Then I chopped power completely causing the jet to pitch straight down and crash. In retrospect it would have been better to ease off the power as soon as the jet pitched up and then keep enough power to hold the nose up but not so much as to climb. At least the crash would have been from a lower altitude.
During the second incident I found the jet at about 3 feet of altitude and was able to modulate power and back the plane down to a tail first landing. What was different was the CG was more forward, there was a 10 mph wind over the plane's surfaces and the nose was only up about 45 degrees.
