>So, would it be correct to type the SR-71 engines as a hybrid turbo-ramjet?

In some circles, it is referred to as a Dual Cycle engine.

Here are some interesting engine tidbits:

- In cruise flight (Mach 3+) the engines grow 6 inches in length and 2.5
inches in diameter.

- At full thrust running at Sea Level, each engine consumed 65,000 pounds
of fuel per hour.

- The SR-71 was more fuel efficient at altitude and high speed, contrary
to all other type of aircraft.

You know, even though this thread is off topic, there are some parallels
with the Newton.

For example, the Newton:

- Incorporated technology that was ahead of it's time.

- Was retired while it still has life in it -- still in use 4 years after
it was discontinued by Apple.

- Still has the best HWR out there, bar none.

- Ran for a long time on batteries -- totally unheard of at the time.

- Allowed for rechargeable or regular battery use.

- Allowed for alternate screen orientations. The Pocket PC devices are
just starting to do this as well as the Palm OS devices by Handera and

- Was capable of voice recognition.

Anyhow, I am sure glad that there is an Apple...

...Otherwise the PC world would be boring... ;-)
