Much of the Hi-res photo collections available on Google Earth are taken from aircraft and not satellites. I think this shadow is from a photo recon aircraft (P3 , is it ?), while the blurry bit is someone on the runway. Given that, the recon ACs shadow would be more steady relative the camera than the landing or departing aircraft on the runway.
Coords I used for Google (decimal degrees):
52.1713N 4.4283E
If you punch in the DMS coors as decimal, Google earth shows a lovely
channel with great detail.
Anyone know to whom the boat shown belongs and where they are going ?
looks like fun to me.
