Many years ago I witnessed a fatal accident following an unnecessary steep takeoff:

I was one of the first on the scene and pronounced the pilot dead.
In my professional career (anaesthetist) I attended many gruesome occurances (stabbings,shootings,RTAs etc.). However this needless loss of life, on what had been an idylic autumn fly-in at my local strip, haunts me to this day.
Please resist the temptation to show off on take-off.
Safe flying
