Umm, I saw it this morning and thought wow, but now I read some doubts, I too doubt,
If one was on the threshold, directly behind and the aircraft was climbing up through a level of fog, wouldn't that cause the effect?
Fog can gather in valleys and low areas, bee quite dense and then one breaks through it. You can see that where the aircraft has punched through it.
It could have been taken from the next aircraft to take off, we dont actually know how far away he is from teh photographer and Trailing Vortices move down ward and away from the aircraft - if I remember correctly.
still - its got us taking about it anyway!!
Hay Ewe - is that real?
