My parents have a small cottage up in the very north west of Scotland. The MOD frequently do low flight training up there. Twice I saw them do incredible stuff. First time was out on a hike and was eating lunch of sandwiches while perched near the top of a waterfall that went down into a steep but narow gulley. Two planes in quick succession flew below where I was sitting through the gulley, angled at 90 degrees so they could fly through it safely.
that's pretty cool with them flying below you. what type of sandwiches did you have?
