The shuttle landing strip at the Kennedy space centre is pretty long. Can't quite remember how long bu the fact that it's known as 'the three mile runway' is a clue.
Istres is the French test facility - a bit like Farnborough was so I expect that is why it has so much runway. And runways of 4000m are common in the gulf. Landing a 747 classic freighter with steel brakes at MLW uses every inch!
