54 years after I had it rammed into me I still remember the take-off check list I learned for an Auster, or indeed any other small single-engine aircraft.
It started with Trim,Throttle nut, Mixture, Pitch, Fuel, Flaps etc etc.
Not all the items were needed on every aircraft. But the training was such that it would have been, and still is, impossible to turn into wind and go without going through the checks.
Leaving the ground with insufficient flying speed is a feature of take-offs on many bumpy grass fields.
I have little or no sympathy with the pilot, and a great deal of sympathy with the woman injured by his carelessness.
The WWII abbreviation to "Fuel, Fan, F*** Off" was necessary at the time for scrambling fighter pilots. But no-one else.
The predictable chorus of "There but for the Grace of God....", "We all make mistakes....." and so on simply softens the lesson that when you fly an aircraft you cannot afford to make mistakes, and if you think that careless mistakes are forgiveable you should stop now.
