The US government has confirmed the 748 as the next presidential aircraft. An airline cancelled their order at the last minute after their aircraft was already built, and the US government purchased it. Should be interesting to see what they do with the extra space. An actual presidential bedroom would be a start, rather than a convertible lounge/bedroom. More space for relief pilots too (and only two pilots required).
Here is a stupid question... Is there some add on you can add to a customized plane that reduce the pressure incomfort in the cabin? Like when ever I fly my ears pops all the time worst when I'm sick... Can that be reduce by adding something that is just not available on commercial aircraft?
I don't think so. Some newer aircraft (A380, A350, B787) have fuselages which allow for higher cabin pressurization which will will reduce the discomfort somewhat but if the fuselage isn't designed for higher pressures you cant retrofit anything to it. Stick with nasal decongestant.
