Reading “the Vulcan Story” by Tim Laming and surprised to see under altitude limitations “There is no height restrictions on the aircraft because of airframe limitations. However, the maximum operating altitude is limited by the oxygen equipment as follows: ……..”
It then tabulates the various combinations with 56,000 feet cabin altitude being the maximum. With a maximum pressurisation differential of 9 PSI surely the bomber boys would have bragging rights over the Lightning altitude attempts on a recent thread. What was she capable of? I’m sure in true military fashion some one must have attempted the official limit plus a bit.
