Hi Megan,
Incontrovertible. No such thing, sorry. Maybe in 101.
From the aerial, I can make a supposition subject to evidence re the embankment scar.
1. If the wingtip, there is no possibility propellor ruts would be symmetrical. (allowing a GS calc...)
2. If the wingtip, there is not enough mass to disrupt the rails to such an extent.
3. If the wingtip, the width of the scar would be much narrower, the scar is too wide.
4. Supposition. Number four experienced catastrophic mount failure, was hanging low, and tore up the embankment prior to wing contact.
From the audio: "have you...." (Feathered four?) "we cannot recover the right roll"
5. How were the aileron cables and boost reconstructed to determine a "fatal flaw"
6. What was the argument that supported two months of aileron duty as serviceable until the fatal launch?
7. Could Lockheed have survived another aircraft loss due to engine mount flaws?
8. Clear your mind, look closely at the scar, and give your consciousness respite from "incontrovertible".....
Best regards,
Concours
Craig: "The plane's stall angle in a bank was about 63 degrees that day, by the way. They were descending not because they were in fact stalled, but because they were feeling the shaking in the controls and knew a stall was near, and they were fighting to keep the speed up by keeping the nose down. Rolling left, close to recovery, they ran out of air."
The aircraft was crossing the ground at 160 knots. What was the wind? If you dismiss the radical roll angle, you should question your consideration of Stall? If so, we need a source for "shaking in the controls...." "Rolling Left, close to recovery...." Does this contradict the CVR "cannot recover the right roll...." Final words, "have you...." (?) this interrogatory suggests a belief in recovery, however remote. My best guess given the controversy here as to roll angle might be "have you feathered four?"
BTW. If Propellor hit first, and included the powerplant (it would), it becomes clear the wing tip may have risen immediately. Why? Once integrity of the spar is lost, all the lift being generated by the wing outboard of #4 instantly lifts the outer wing, clear of the embankment...
