Recently saw this article about a partial ejection:
Irish Luck - Surviving Partial Ejection from A-6 Aircraft
This has led me to wonder (don't ask how) whether or not the cockpit of a fast jet is pressurised?
An 'educated' (or then again maybe not
) guess would lead me to say yes for comfort among other things, wondered if anyone could shed some light?
If this is the case then what purpose does the mask serve?
