Good question Nipva.
I've never flown the Typhoon, but having just googled the service ceiling (and who knows if the stated information is true) and it's given as 65,000'. Taking into account that, just maybe, the publicly available performance figures might be a bit on the conservative side of the actual capability, it still seems that it would be unlikely that what you watched was accurate. I tend to agree with the other replies - it was most likely corrupted data.
Never mind the sad saps like 'Salad-Dodger'; keep watching PF or FR and enjoy the interesting things that can be seen every once in a while.
