I've been _blown_over_ by propwash from a low Hercules, whilst walking
on Salisbury Plain. The ranges were closed (red flags out), but we
weren't on the range.

B/f has been blown out of a tree by a tree-top skimming Vulcan. What
was he doing up the tree? He lived near an air base and the tree
seemed like a good vantage point to watch the Vulcan take off (which
was also the reason it was treetop skimming).
