This is all, an improbable, 100% fictitious example on my part, but: recall others in the industry in this thread have voiced concern that we are already into a highly unlikely probability with this double engine failure in of itself.
Such as temporary, uncommanded closing of the spar valves perhaps?
In the
Questions section of PPRune an incident was briefly posted regarding a B757 with an engine rollback immediately after take-off. The C/B of the spar valve for the affected engine had tripped but was ok when scanning the breakers during preflight. Any one have any information about the outcome of that incident? As far as i know, no other replies were added to that post after i made the suggestion about a possible uncommanded closure in that incident.
Here is a link to that post:
