I think it's very romantic that people want to think that the SR-71
is capable of going faster than it actually is.
But when you consider it, it's pretty much a miracle that it did
what it did. I just got through reading the Skunk Works book and
after reading about all of the challenges they went through to make
that airplane it's amazing it exists at all.
However, I always wondered if with all that we know now about
materials, propulsion, fuels and structures and with the super-
computers we have if they couldn't create something comparable
or better.
The problem is, after reading the book I know now that it's one
thing to create a really fast airplane - the other issue is surmounting
not only technical challenges, but political challenges.
It was sad to read about all of those in Washington who were against
its being made, and the many attempts to shut it down which eventually
did work.

The NASA SR-71 Researcher's handbook has a chapter on what modifications
would be required to allow the aircraft to got M=4. Unfortunately, my

I told someone at NASA, probably Mary, that if I won
several million bucks in the Illinois lottery, I would
pay as much as $1,000,000 for a VIP ride. No dice.
And since my wife has "line item veto" status, I'm
sure she would have me committed to the nearest mental
health facility!
My last hope is to get invited to sit in the cockpit
of 976 at the USAF museum. But that too is probably
unlikely as the ice cube in hell.
Oh well, such is life.

Mach 3.6? That's faster by a bit than the info I've managed
to find. An A-12 was said to have reached Mach 3.56 but only
very briefly. Another source told me that an SR-71 went to
Mach 3.4 but the shock waves from the nose messed up the
airflow into the nacelles. This caused an unstart, I think
on both engines. I believe the pilot did get the engines
going again after slowing down a lot. The plane made it
back to the base. Someone posted a note about a YF-12
flight that sounds similar to what I described so I'm not
sure if these are 2 separate events or just 1 with maybe
an error or two. Could be I'm the one making the errors.

Hello Frank,
I checked a few other online bookstores, but no luck either ...
Anyway, I got the book from the mail order service of Midland Counties
Publications (UK). Since they happen to be the publisher of the book,
they've probably got a head start ;-)!
They have a _very_ new (since a few days) online shop at
http://www.ianallansuperstore.com
but the title is apparently not yet entered into the database. However, you
can order it by phone, fax or e-mail. Strangly, the e-mail address isn't
listed on the "Contact" page of the site, but AFAIK is still valid at:
midlandbooks@compuserve.com
The "Info" page on the website gives details about delivery options, costs
and times.
Hope this helps!

Subject: RE: SR-71 & Hypersonic Flight
I'm reposting something I posted back in July of 1999 that addresses
this issue.
From CIT max, ie: what is given, it's quite easy to estimate the SR's
top speed if you understand the physical process that is occurring before
the compressor inlet is reached. In fact, it is so simple that it could be
easily added as a quiz question to a first aero class course if the
professor explained the supersonic diffusion (inlet) process.
Given that the supersonic diffusion or inlet process slows the freestream
flow before combustion from freestream velocity to about M .2 or so, one
can use the stagnation temperature equation to estimate the physical effects
of this process!
So all of you, go lookup this equation. An additional benefit of this equation
is that one can see the effect of cooler ambient temperatures at different
altitudes on ultimate Mach No!
Use:
T0 of 700 degrees K (CIT max, per SR Dash-1 and Bill Brown's Lockheed
Horizon's piece.
T of 219 degrees K (ambient temp at roughly 85,000 ft)
Lambda of 1.4 (Ratio of specific heats)
Plug them into the stagnation temperature formula, and solve for
Mach No.
The answer I get is: Mach 3.32 !! Pretty darn close!!
In fact, in the Lockheed Horizons piece by Bill Brown, he mentions 100,000 ft.
I recalculated using 232 degrees K for ambient temperature at 100,000 ft.
The answer comes out to Mach 3.2, with a CIT of 700 degrees K at 100,000 ft.
Ah, the benefit of cooler temperatures!
>>>Blackbird was flying right on the hairy edge as it was. The
>>>limiting factor that I recall was the design of the canopy.
>>>Apparently it was close to self destruction at the low to

You may be thinking of the XF8U-3 here. A quite capable Mach 2.8 airplane
that achieved its speed with a FIXED COMPRESSION inlet, unlike the SR's inlet
which was VARIABLE. And it predated the A-12 by around 3-4 years I think.
There's interesting food for thought when one compares the two inlets
on those two airplanes.

I just spoke with Jay Miller, he said he hasn't even received a copy yet!!!!
Jay said the importer is actually Specialty Press (which I think is the
same as Midland Counties but not sure). He didn't have any other

X-33 chapter alludes to the possibility that the X-33 might be cancelled

The X-33 had the smell of death about it for the last couple of years at
least. There was some early hope that the program wasn't so much for
development and demonstration of several new technologies as for bringing
them out of the black world. Alas, that seems to have been wishful
thinking. For those who have access to Usenet archives, pertinent
discussions were carried on in sci.space.policy.
One hopes that a book is written about X-33. (This is a hint for a certain
author who has delved into the F-18 E/F and A-12 stories. :) )

Larry,
This was always a good post - even back in 1999!
I am curious if anyone has done a sensitivity analysis where you vary the
CIT max in increments of 5 or 10 degrees and observe how much the Mach
number varies. I am not a conspiracy theorist by any means; I am just
curious how the Mach would vary if say the real CIT max was for example 720
degrees K rather than 700 degrees K.
One note - I am not an engineer and have never taken an aero class (and do
not have the formula in question); otherwise I would do this myself.

The X-33 had the smell of death about it for the last couple of years at
least. There was some early hope that the program wasn't so much for
development and demonstration of several new technologies as for bringing
them out of the black world. Alas, that seems to have been wishful
thinking. For those who have access to Usenet archives, pertinent
discussions were carried on in sci.space.policy.
One hopes that a book is written about X-33. (This is a hint for a certain
author who has delved into the F-18 E/F and A-12 stories. :) )

Anybody know about this website?
http://www.edmgroup.net/habu_index.htm
Its a Habu dedicated website.
Has some photos of the event as well,
http://www.edmgroup.net/photos.html
Kind of looks like some of the people are get'n older now.
It would have been nice to have some captions under each photo, with names
and memories, etc.,
for the rest of us who were not there and who don't know perhaps a lot of
the attendees by name and face.
Take a look at the list of some of the attendees, for the "HABU 2000"
