Well, if the MiG-31 pilot takes a pressure-suit, it can take nearly forever to get ready, since to put that on you've gotta strip down to your skivvies, and find an extra set of hands to pack your meaty frame into it.
-Or the pressure suit [i]is[/i] Lonnie's skivvies, in that case getting ready is pretty quick and simple.

Seems the latter case usually happened if one expected to be on-alert for that day, stripping-out soon as you got off.

Which brings about the problem of pilot-hygiene during sustained high-intesity operations. (which during the cold-war, also had to consider the possibility of fields being chemically contaminated and/or irradiated)

[u]Also: MiG-25 as a ground attack jet:[/u]
"As the bombs would weigh no more and incur no more drag than its regular load of R-40 missiles, its performance was not impaired, leading to some impressive bombing feats; when released at an altitude of 20,000m (66,000 ft) and a speed above Mach 2, a [normal] 500 kg bomb would have a glide range of several tens of kilometres"

Blyat. MiG-23 wanna try.
