Hi Tom
He is reaching around the prop but also he does not have the plane staked to the ground !!! Guess he never had one covered with exhaust residue to slip through his fingers. At the angle he's starting the plane from he might get a bit more than a chewed up hand [X(][X(][X(] If that plane starts forward and the wing hits his right leg it will turn straight into him. ( Seen it happen )
Not to mention that if the prop breaks he's got a pretty good chance of getting hit with it.

The guy on the video is a complete moron ; NEVER attempt to start an engine this way. There are plenty of ways to get hurt in this hobby without asking for it.
