Seeing as this is not the first time something similar has occured (plenty of pictures on the web to testify) - it may be past time to address.
Once the art of hand starting was common practice - hands up who knows (through training) how this is done? This is something I have never done and don't think I would attempt without really understanding what I was doing - considering the consequences of an error.
Does the procedure of hand starting need to be part of the syllabus when learning to operate flying machines?
or:
Discourage the practice completely.
