I wonder if the true ceiling was perhaps somewhere between the two figures quoted ?..It would be interesting to hear from ex aircrew types................

Thank you,

For ex aircrew you probably need to ask that question on prune
A Google search suggests 56K is probably about right, additionally similar searches for aircraft like the Canberra PR9 suggest that 80k is unlikely
I did see a Vulcan pilots notes on eBay the other week, although I was a bit suspicious about it. The service ceiling must have been below the maximum to allow for varying conditions at that height. It would be interesting to read the test pilots version as that may be where some of the higher figures stemmed from, although I would have thought 80,000ft is still way too high. Would it also depend on mark and engine version as I seem to recall engines having a ceiling independent to the airframe but that must be a formula driven height?
No Amount Of Evidence Will Ever Persuade An Idiot (probably not Mark Twain)
I think ultimate ceiling is pretty much only to do with engines and air intakes. They need oxygen and without it they can't function. Different engines perform differently in the rarified atmosphere.
Having said that a big heavy airframe needs to be kept up in the air when there isn't much air to create lift. So lots and lots of engine power is needed.
That's probably why it's the smaller planes that got higher (x-15, starfighters,phantom)
The Olympus 301 was derated for normal service use,more power was available from the engine and I was just wondering if the aircraft may have been used for some sort of intelligence/probing mission..The North Cape is very close to the former Soviet Union ...probably a load of nonsense on my part !
Thank you all for the informative remarks.
