Shy's post reminds me of a well known tale told between Hang Glider folk when the wind's off the hill and we all know the day is over but don't want to go home. Apparantly it is true.
I guess it could have occured in any arena of low speed aviation - its components are one HG pilot at the end of a 50 mile difficult XC, failing vis, tired pilot and a model village.
Yes, you have it, pilot (circling over village whilst setting up for landing) thought he was at 500' and next second ploughed through Churches, houses etc in a spray of lego bricks.

PS B, it wasn't blue but it nailed itself to the ariel.
