One of the gravestones at the Trafalgar cemetery.
Staying on the theme of Gibraltar, in the 80s when I was test flying, I had to go out to Gib once a year to test fly the Lynx helicopter that was based there. The first few times the border was closed, as it had been for many years but on the last trip, the border had been opened. What a revelation that was. I flew out on the military trooping flight on a Thursday, did the test flight on Friday and couldn't get home until the next Tuesday. The weekend is classified.
The airfield at Gibraltar. Just to the north is the Spanish border and when the Spanish were being anal (most of the time) you had to be extremely careful not to fly into their airspace. It meant a curved approach to the runway which even in a helicopter could be interesting as it brought you into the lee of the rock and the turbulence could be fierce.
