I recently found on my computer this photo taken during a trip to Gibraltar in 2005:
This is the barrier where the sole road into Gibraltar crosses the airport’s runway. (The airport terminal is in the background in this photo.) The road and walkway are closed during the few times a day when a plane is landing or taking off. I case you can’t see clearly, the signs say:
Pedestrians are to keep within the white lines.
Please cross quickly.
Litter can cause aircraft accidents.
Put your litter in the red bins.
Keep the runway clear.
It’s a bit surreal walking across an active runway. Gibraltar is a great aviation destination. Below the fold are a few photos from the terminal, through which my traveling companion and I departed the Mediterranean coast and returned to London.
