Beat me to it! I was about to metion Istres, which is the French equivalent to Boscome. It lines up with the local valley so that when the mistral blows, you have a headwind. Last time I landed there, we had a 60 knot headwind which made all that concrete rather superfluous.
And as for Sculthorpe - the RB45s operating from Sculthorpe carried RAF markings and registrations. These flights were as a result of John F Kennedy's statement to congress that the CIA and USAF flights over the USSR would be curtailed. The solution - get someone else to do them!
The Sculthorpe optical illusion was quite marked. Like a lot of military runways, the first 1000' at each end was concrete with the rest being tarmac. This gave an illusion of sorts but was increased by the undulations at Sculthorpe. I don't remember it being particularly long, but I was in a Victor. All runways seemed short when landing the Victor!
