Every single crash listed in those links where the crew successfully bailed out and survived was at less than Mach 3, the majority of them at subsonic speeds on takeoff, landing, or tanking approach.

When his SR-71 Disintegrated, This Pilot Free Fell From Space & Lived to Tell About It - CHUCKYEAGER.ORG
During the early days of testing for the legendary SR-71 Blackbird there were some harrowing mishaps, the details of which have rarely come to light. On January 25, 1966, test pilot Bill Weaver and Lockheed flight test reconnaissance and navigation systems specialist Jim Zwayer experienced their...www.chuckyeager.org
The link in my other post speaks to the low air density at those altitudes requiring a drouge chute to stabilize an individual who has bailed out at those altitudes to avoid damage by excessive G forces due to un controlled spinning, so I am inclined to believe that ejections at those heights and speeds could in fact have been survivable.How many ejections from a combat damaged aircraft at Mach 3 did this source have access to in order to asses that?
That is not how I read it... My take on the account was that the SR71 disintegrated at high speed and high altitude before the survivor could decide to eject.. It also specifically speaks to air density at high altitude being in sufficient to prevent a human from tumbling..Thats the same story from the first link. Note the pilot mentions specifically waiting to eject until their speed reduced to a manageable, survivable one.
How many Mach 3 air craft have actually been damaged in combat ? For that matter how many actual Mach 3 combat missions besides SR71 and Mig 25 overflights have actually been flown ? I doubt the sample size is big enough to draw meaningful conclusions about ejections from combat damaged air craft at Mach 3.How many ejections from a combat damaged aircraft at Mach 3 did this source have access to in order to asses that?
It says that they planned to wait until they were at lower altitude and slower speed, but that the vehicle actually disintegrated at high altitude and speed, forestalling that option. Specifically,Thats the same story from the first link. Note the pilot mentions specifically waiting to eject until their speed reduced to a manageable, survivable one.
Since the chances to survive an ejection at Mach 3.18 and 78,000 feet weren’t very good, Weaver and Zwayer decided to stay with the aircraft to restore control until they reached a lower speed and altitude, but the cumulative effects of system malfunctions exceeded flight control authority. Everything seemed to unfold in slow motion, even if the time from event onset to catastrophic departure from controlled flight was only two to three seconds.
Weaver struggled to realize what was really happening. “I could not have survived what had just happened. I must be dead. As full awareness took hold, I realized I was not dead. But somehow I had separated from the airplane. I had no idea how this could have happened; I hadn’t initiated an ejection. The sound of rushing air and what sounded like straps flapping in the wind confirmed I was falling, but I couldn’t see anything. My pressure suit’s face plate had frozen over and I was staring at a layer of ice.”

That's different than a Blackbird peppered with shrapnel from near 500 pounds of HE from a SA-5 Gammon exploding nearbyFor another example, one could look at the ejection from the M-21 that followed its collision with the D-21 drone after a launching attempt. The collision and subsequent ejection occurred at Mach 3.25 and 80 000 feet; both crew members survived ejection, but one drowned after splashing down. The evidence is clearly that a high-altitude, high-speed ejection from the SR-71, while obviously dangerous, is entirely survivable. Therefore, the crew members of the SR-71 in this thread certainly have a chance of successfully ejecting and landing in Soviet territory.
And? So what? The point of the examples is to show that it is possible to survive being ejected from an SR-71 at Mach 3+ and high altitude, which they do. I never claimed that it was certain that the operators would survive, only that it is plausible because they actually did survive ejection at similar speeds and altitudes.That's different than a Blackbird peppered with shrapnel from near 500 pounds of HE from a SA-5 Gammon exploding nearby

If said shrapnel punctures a pressure suit (or suits) I suspect the air crew are unlikely to survive. Shrapnel from SAMs is typically intended to penetrate targets, whereas the effects of a disintegrating aircraft or a collision are probably a bit less predictable.And? So what?

Besides, I fail to see how being "peppered with shrapnel" is necessarily worse than your aircraft going out of control and literally disintegrating around you or hitting another aircraft a large fraction of your own size while you're both traveling at Mach 3+.
Sure. And the operators are sitting in a large aircraft that has a pretty good chance of stopping such shrapnel from reaching their pressure suits (especially if the missile doesn't explode particularly close to the cockpit). In the case of the aircraft disintegrating, the aircraft itself is trying to kill them.If said shrapnel punctures a pressure suit (or suits) I suspect the air crew are unlikely to survive.

There were close calls. In fact the only thing that saved the plane in '87 was the Swedish escort to Danish airspace. Certainly the Swedes had the capacity to shoot intruding Blackbirds down if they felt the need.
So 6 MiG-31s form a circle around the SR-71 and then fire their long range missiles into the centre of the circle. What could possible go wrong? I hope those MiGs have robust IFF.... six aircrafts were to box in the SR-71 and fire R-33s from multiple vectors and hopefully one hit would be scored.
SR-71s were not invulnerable. The BAC Lightning managed to intercept them from above several times. They adopted a ballistic profile and descended on the Blackbird without warning. The Lightning also successfully intercepted U-2s and the Concorde. Both extremely difficult targets.
