Can anyone tell me what the highest absolute ceiling of production aircraft
is? I know the Lockheed U-2 could go to 70000ft, but I'm pretty sure I've
seen somewhere that some Russian fighters can go to 60000ft. The service
ceiling I've seen quoted online is 50000ft though. Anyone have better
figures? I'm taking it that the fighters can do climbs to extremely high
altitudes but only in an arc where they climb up and fall back down.
Thanks,
David

For sustained flight, the SR-71 Blackbird could cruise at 85,000+
feet.
That record was set many years ago (1976 AFAIK) and may have been
eclipsed by now.
Likewise the SR-71 Blackbird also held the absolute speed record of
1906 knots (2,193 mph, 3,530 km/h) at that time.

Its reported that the English Electric Lightning reached 93000 ft in a
ballistic arc so it could dive on an unannounced U2 over the UK.

Perhaps this is a good time to dredge up these gems...
In his book,"Sled Driver" SR 71 Blackbird Brian Shul writes I'll always
remember a certain radio exchange that occurred one day as Walt (his
backseater) and I were screaming across Southern California, 13 miles
high.
We were monitoring various radio transmissions from other aircraft, as
we entered Los Angeles airspace."
"Though they didn't really control us, they did monitor our movement
across their scope. I heard a Cessna ask for a readout of its ground
speed. "90 knots" Center replied.

That's pretty impressive, and basically what I was looking for, production
fighters that go really high. Thanks,
David
