I did hear about a competition in France where quite a few gliders landed out a few miles from home in the same largish field. The tug arrived to retreive them one by one back to base. Front of the queue was a large German chap in a very heavy glass glider. The tuggie looked at the glider, the pilot, and the field length, and shook his head. "Non".
The German insisted, so he was hooked onto the tow rope and they set off, the tug at full chat, down the field. When about 20 metres from the hedge the Tuggie knew for sure that the glider wasn't going to get off the ground in time so he released the tow, hopped over the hedge, flew a tight circuit, and landed back. Meanwhile the heavy glider ploughed into the hedge in a shower of disintegrating fibre glass.
Tuggie taxied up the waiting line of gliders.
"And 'oo ees next?".
