came across this link on another aviation webforums in a discussion about the Redbull freefall attempt, discussion had turned to the subject of high (supersonic) speeds and their effect on the human body, and the ability of a suit to protect a pilot or astronaut at such high speeds.
read this account, and was completely in awe.

Test pilots for sure had solid titanium balls.
:eek: :eek:

Wow!
Thanks for sharing!
-
Great read.
-
pretty amazing.. :aok

SR-71 was a fantastic plane but traveling at Mach 3.2 right on the edge of a stall made it a handful and dangerous.
-
thats friggin crazy :O :O
-
Thanks for posting that.
-
Wow.

and the hand of God plucked them from the wreckage and gently placed them 1.5 miles from a rancher with a helicopter....
Awesome story!!!! I am definitely sharing this with others :rock

truly amazing and a great read! Thanks for posting :salute

Too bad, Jim died. :(

server hiccup :/

Yeah... The hand of God snapped his neck and gently placed him 1.5 miles from a rancher with a helicopter....
...
Amazing survival story for the pilot though. Truly remarkable!

holy cow :O

Good read, thanks.

Sorry....I left the article and came back and started a paragraph lower...

Was the OFFICAL speed for the SR-71 ever de-classified???
-
Yes. Ludicrous speed.
-
Yes. Ludicrous speed.
THEY HAVE GONE TO PLAID!!!!!
no but seriously that man is lucky as heck, i would have crapped that suit if i were him......if i had the ability to crap myself at 70,000+ alt

The highest noted speed is 3.5 Mach
The fastest published speed of the SR is Mach 3.5. There are several factors that limit the speed of the SR, one is the shock waves generated by various parts of the plane, at around Mach 3.6- 3.8 the shock wave off the nose of the aircraft narrows enough to go into the engine, while there is the inlet spike (which slows the air to subsonic before it enters the engine), the shock wave bypasses the spike and causes the engine to unstart.
Second is the heat generated by the plane moving through the atmosphere, even titanium has it's limits, and the heat generated by the SR brings the fuselage to the brink. Just recently I found out that during a Lockheed Skunk Works study to see how much money and development it would take to get the SR to go faster than it's designed top speed 3.2- 3.5, the designers discovered (among other things) that the metal divider between the windshield was heating up so much above mach 3.5 that it was affecting the integrity of the windshield, and at that point they had stretched the glass technology to the max! So Mach 3.2 to a max of 3.5.
Now according to Richard Graham: "The design Mach number of the SR-71 is 3.2 Mach. When authorized by the Commander, speeds up to Mach 3.3 may be flown if the CIT limit of 427 degrees C. is not exceeded. I have heard of crews reaching 3.5 Mach inadvertently, but that is the absolute maximum I am aware of."

In other words it COULD go faster, but the plane would fall apart.

Since the topic is turning to "speed", I remember seeing the story in the above link in an email. Not sure if this is an urban legend but the story is funny...
Now back to the regularly scheduled program... :aok
