Hopefully this dispels any of those kooky theories about the F-15EX getting a different engine to what the SA and QA use. Also, this should put a damper on the F-15EX carrying a hypersonic missile. Maybe in the future, but looks like for now, the B-52 is designated, and B-1 loser to fruition. https...

You do not need plumbing for PSU. The PSU have self contain oxygen generators. Palletized seats can be used on the KC-46 and can easily be used on any 747F.

From what I can see, palletized seats are not as efficient in space usage as regular passenger transport.
