On est d'accord. J'ai d'ailleur cité le propos d'un pilote de F-15 qui signale qu'avec un emport assymétrique, ou une mauvais répartition du fuel, avec trop d'AOA, il part en vrille à plat irrécupérable.
In my opinion, having flown the F-15 for 15 straight years, and having seen a few accidents along the way, that jet looks like it hit the ground with no forward velocity at all. The most probable way for that to happen is not if it got shot down, but if it was out of control in flat spin. And the most probable way for that to happen is if there was a large lateral imbalance ( like a full and empty external wing tank ) and too much AOA or Gs. The aircraft would enter a flat spin and many times is not recoverable.
However, it is reported that the crew ejected at high altitude. That is not consistent with a spin ejection.
There are few mechanical failures that would cause the crew to eject at high altitude and have then aircraft hit the ground in a flat attitude with no airspeed. In fact I can't think of any that would cause that.
It looks like it had plenty of gas when it hit the ground.
My guess is that it was in a spin and they bailed about 10,000 feet and somebody considers that high altitude. It is high enough to cause separation of the crew on ejection and it's the standard out of control ejection altitude.
That is the only thing I can think of to cause it to hit the ground with no forward velocity, intact in the same spot and no crater. I doubt it was hit by enemy fire.
ETA DISCLAIMER: I was not a safety puke ( spitting to the right )
ce à quoi a répondu un WSO de F-15 :
agree with your points but our CAS controls are different than the C model, its nearly impossble to spin our jet (even with imbalenced external loads). I doubt it was a spin becuase of what they were doing. I would put money on ejection from a trimmed aircraft and it "flew" into the ground vice the lawn dart strait in type crash.
If it were a spin, there would have been more lateral scatter of parts
We shall see in the SR
plus tard, le premier signale ceci :
Keep in mind an Israeli F-15 lost an entire wing at the wing route in a mid air collision and the pilot landed it with only one wing.
There was an F-15 that hit a guide wire of a 1500 foot tower when I was at Tyndall AFB and the jet lost all functions on the left side of the jet: engine, gear, all flight controls and hydraulics on the left side were cut from the jet by the wire and the pilot cam back and landed.
An F-15 in Alaska was hit by 2 Aim-9M right up the engine accidentally shot by his wingman and both engines kept running and the pilot came back and landed.
A St Louis ANG aircraft had a midair with an F-16 and lost 3/4 of the right wing and he came back and landed.
I lost the entire forward half of the right horizontal stabilizer in flight and never knew it. I landed and noticed it on the post flight.
I landed, the right gear collapsed and I went around on the right wingtip, the centerline tank, and the right horizontal stab all in contact with the ground and the jet got airborne and flew just fine with a cracked wingspar and significant damage.
It is a very survivable jet and can suffer a lot of damage and keep flying.
I don't think it's likely that it was hit by AAA or a missile and then lost all it's airspeed and pancaked it. If the nose drops, it would pick up airspeed and leave a hole in the ground with parts spread out for a long distance.
This thing hit the ground falling like a leaf in a flat attitude. The only way I know for that to happen is a flat spin, and the most likely entry into that is a lateral imbalance due to fuel or stores and some high AOA.
But like I said, It;s just supposition on my part.
quand il a vu la réponse du WSO, il a ajouté ça :
I was not aware of the CAS difference.
If it flew into the ground, it would have had some decent forward velocity,, the ground behind it doesn't look like it had a jet skidding across the ground. The pylons and missile parts are all in the same spot.
I have seen some pics of jets fly into the ground level and there are usually parts along the trench made by the metal sliding along the ground. I just don't see any of that here.
If the CAS was lost would it be easier to spin with a lateral imbalance?
