Remember, the B-47 did their immelmans from high altitude (and entered from a
dive obviously), the Afghanistan Bone would be entering from straight and
level, thus it becomes an excess thrust issue.

See below.

Well, fly around the pattern trailing a parachute is one...
Tobogganing behind an overstressed KC-97 would be another.


Cruising around, fully loaded (albeit a smaller load than a BUFF or Bone) at
40K+ and .90 mach.

Nope. B-47E SAC: Max. Spd, 606 mph (M0.84) @ 16,300 ft.; 557 mph (M0.842) @
38,550 ft.; Max. cr. spd., 495 mph (M0.75) @ 38,550 ft.; Svc. Ceiling 40,500 ft.

Doing an immelman at high altitude (not possible for a
BUFF...maybe for a Bone, but not from 30K+).

The Immelmanns were done from the deck while making LABS tosses, starting in
1957. They went down there for the same reasons the B-52s did: defenses had
driven them from high altitude to low. There were 6 B-47 crashes in the spring of
1958 brought on by fatigue failures due to these and pop-up maneuvers, which is
why Project Milk Bottle was instituted, to replace the wing milk bottle connecting
pin.
