gonebutnotforgotten (post#185), the only thing you have not covered in your discussion of the descent from TOD to 600ft is the denouement.
Is it plausible that the 'plug of wax' (which you liken to an embolus) could affect both engines, when they are being fed from separate autonomous tanks? If not, there would have to be two plugs of wax evolving separately and independently.
Plausible enough, but is it likely that they would each migrate to the two engines and cause their separate failures at an interval of only 8 seconds?
You don't believe it either, do you?
