That depends on the rout your plane takes.
No, from London Egypt and Greenland are in the opposite direction.
You can fly from London to San Francisco without flying over Scotland on the plane by flying from London to Portugal first. You might also fly from London to Paris and then from Paris to San Francisco.
Flying from London, you have to pass over Queens before you pass over Brooklyn. So, Queens is closer to London than Brooklyn.

No because even if they fly above London, they have not stood on london's ground. So no.
I have not noticed ANY countries flying over Oman.
Apart from the UK and the US, you might also fly over Ireland depending which UK airport you're flying from.
Probably Germany, France and Italy.
