Yesterday, I was in my yard when I saw two large aeroplanes heading west,
they looked like International Flights..
and I thought it was quite odd that they should be so close together.
They both seemed to suddenly thrust there jets, as if getting out of each others way.
So I ran inside and got my camera and took some shots...of the trail they made.

Can anyone tell me, for what reason would this happen?
and...Am I right in assuming, they were in each others air space??
There was nothing on the news...it has me baffled!
