How close is acceptable???
I would be interested to know how close 2 aircraft have to be, before it is classed as a near miss? I ask this, as I watched 2 747's flying nearly parallel to each other (200M - 300M) and on the same level, with a gap of 100m tail to nose max. I reckon they were at the bottom of a stack that builds over my home (Cowfold - Henfield, south of LGW). I estimated their height at 5-6k. This was on Sat 27 Aug @ 8.30 ish.
One 747 was a Virgin Atlantic, not sure of the other. I thought they maybe taking photo's??
Honestly they were very close to each other, this is the closest I have seen 2 civilian aircraft.
I have enjoyed reading this forum for many, many months, BUT do not feel qualified to post as not being a pilot myself.
