I thought center gave vertical and horizontal separation for birds on
same over water route?

They do.

Didn't they a few years ago reduce vertical
separation from 2K to 1K if certain (new accurate alt measuring)
equipment was on board the aircraft to increase (double) traffic
density on the overseas routes?

Yes, it's called RVSM = Reduced Verticle Seperation Minimums

If flight was direct from way point to way point then I doubt if the
birds came within visual range??? Would be an odd throw of the dice.

Huh? With all do respect, I do this for a living and there are "birds"
somewhere in the Flight Levels that come within visual range of each other
(both same and opposite direction) every minuite of every day. We are often
able to visually identify company paint schemes and aircraft types (again
both same and opposite direction) all the time. There is nothing odd about
it at all. Plus, with the 1K RVSM sep that you talk about above, it would
be even easier.

That said, I can postulate a situation where two birds with a few
thousand feet vertical clearance going the same direction on the same
route and with different cruising speeds, slowly pass each other and
BA be able to recognize the distinctive paint job on AF1. This in day
light of course.

In the real world "birds" don't just flash past each other in the FL's in
the blink of an eye. Even if opposite direction you usually have several
seconds of good visual (weather conditions permiting, of course) opportunity
for an identification.

Tale has a lot of characteristics of a good bar story ...

I disagree. To those of us in the trenches (er, Flight Levels) it has the
characteristics of an entirley plausable event that happens every day.

Good show George.

Agreed.
