I'd have thought you'd have known the MR2 stuff with your background.
But. I guess not. Fairly easy to get a 9 hour stretch out of a full tank of gas. Mission dependent, more.
With AAR crew fatigue was the issue.
P-8 is similar, however the intent is to ASW at higher altitudes, thereby saving even more gas.
I'm curious about your statement though.
Why are you "less and less impressed"?
