Shaggy Sheep Driver (i'm not sure what that name means)
It refers to my Yak 52 flying days, and it's wrong on 2 counts; a Yak is a shaggy cow, not a shaggy sheep. And I don't fly Yaks any more anyway.
Perhaps I should change it - or revert to my real name, as Tricky Woo has.

PS - groundloops; some aeroplanes' undercarriages will take the sidways forces OK. Other will collapse. I understand that Jodels are not very forgiving in this respect.
