Now in all your long career Centaurus, have you never flown a Tiger Moth?
Lots of hours instructing on them in the RAAF as well as crop-dusting. For vertically challenged short arses like myself it was a problem getting a hand to the top of the prop to get a good swing - hence the danger. Hand swing the more powerful engines like Cessna/Warrior types with tricycle undercarriage then swinging those props when they were horizontal could be hazardous.
While I never did it thank goodness, hand starting a Dakota engine could be done using a human chain with the bloke drawing the short straw had his hand on the prop and a chain of others holding his other hand and all pulling together. Better still tying a rope around the Dakota spinner and have a jeep pull the rope to get the engine started.
