I've seen 60,000 plus after a high speed run on completion of an op-shoot at Akrotiri. I was too stupid to realise why he beast and its AEA had a 50,000ft limit. I've also seen 825 indicated. Another woops.
A friend of mine saw what he though was an oil-slick off the Falklands. He went to investigate, and it turned out to be a flock of albatroses sitting on the water. They got airborne and he pulled an estimated 12 G to avoid them. The fletchers got bent, but the jet was back on the line a couple of days later after some checks. It was a tough bird.
