The USN does IFR for fleet CAP right now. However, the crew runs out of
stamina after seom indeterminate time. having spent over 10 hours in an
F4 cockpit, I can tell you I really wouldn't feel comfortable engaging
an enemy after ten hours aloft. The aircraft themselves have aloft
limits; new ones do replenish the oxygen system which was one of the
F4's limits.

The F-111's escape capsule not only had an advantage in supersonic
'ejection' at zero altitude but it allowed a greater degree of crew
comfort. The soviet Suhokoi Su 34 "Platypus", which is an Su 27
derivative, has a 2 crew side by side seating with a little
****ter/toilet and galley in the rear. Very impressive crew cabin
built of 17mm Titanium armour and the abillity to carry rearward facing
AAM's.
