Don't see why not. If the high-altitude designed B-47s could do them
(admittedly,
with some serious wing fatigue problems as a result), then the low-altitude
stressed B-1 shouldn't mind.


It's not a stress issue, it's an excess thrust issue. The Bone may be able to
pull off an immelman,but I'm betting you won't find too many pilots eager to
test out that theory.


If it's qn excess thrust issue, than that would weight it even further
into the "Yes, sure the B-1 can do an Immelman" side. Of all the
things the B-47 didn't have, thrust was probably the most obvious.
According the the B-47S Standard Aircraft Characteristics, Takeoff
Ground Roll for a loaded B-47E-IV, without RATO, could be upwards of
10.500'. That's not exactly a high t/w. (A better context for excess
thrust numbers woudl be SEP at Combat Weight - in that case, the B-47E
data gives us 4450 '/mion @ Sea Level, a 1965-era B-52H gives
6500'/minute. (Score one for the Buff)

For that matter, I've flown planty of Immelmans in sailplanes - it's
hard to find a lower T/W than 0. (Although the roll at the top _was_
kinda sloppy_ What would be more important is Drag/Weight. If you'ge
got a really slippery shape, you won't lose speed as quickly with the
nose high.
If thrust exactly equalled drag (SEP = 0), it'd take _anything_ pulled
straight up anout 260 seconds to lose 300 KTS. Your entry adn exi t
speeds would be rather dependant on the airplane, of course. but
there's plenty of energy for a 2-3 G pull through 180 degrees.


By the way, the B-47 could do many things niether the B-52 or B-1B can do.


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

Now THAT'S priceless. Saw him do his show in an AeroCommander, truly amazing,
engine off loops and such..

Two utterly different issues.

1. BRAC. Someone posted a question. I posted a pretty good reply and
hoped to stir some interest. Result: NADA. We can run a thread for days
about bull****, but a pretty significant issue that will effect many
individuals and military readiness .... nada. Sigh.

2. Shimano. Heard they've run Branford Bike out of the Shimano
distribution business. Hmmm.

They are just whinning along with Lictons, I think. They don't think it's fair
for shimano to try to protect their distribution and try to raise who deals
with their equipment to a higher level. Branford and Lictons are just concerned
about $$.

They could both resell shimano via MO or the internet, they just have to agree
to sell it in a MSRP range, or no supply. Too bad, I like they way the playing
field has been leveled.

I'll tell ya another frustration. I read Kerry's voting record and the weapons
systems it involved. Some made sense(like the B-2) but others didn't like his
nay vote on the F-14A(what keep the F-4???) , F-15C and F-16. W/o those
programs we would have been in deep kimchee for GWI and II.

Bush seems like a deer in the headlights and Kerry seems like McGovern
reincarnated...yikess...
