It's OK and reassuring to pass within gliding range from time to time,
but runways suck gliders towards them. Well known fact.

You obviously haven't flown much in the US southwest. Over much of our
terrain, you can either land at an airfield or crash into cactus or
tree-strewn mountains. Landable strips are an essential part of our
database.

In such places it is obviously sensible to keep landing places in
mind, but I still think it's a mistake to fly directly over them.
There is a strange magnetic attraction at work ...
