I am not a 747 pilot, but is V1 not the mark where you go anyway and do not abort?
V1 is a decision speed.Before it you can stop.After V1 you have to continue.
Very roughly correct in layman's terms only...
However, and I am not saying they had "lost" 2 engines, but V1 as a Go Speed only relates to failure of 1 engine. If you have 2 engines fail, or even one and a bit
just post V1, then the ensuing accident is likely to be far worse / higher speed by continuing rather than attempting to stop
The press quote above appears to indicate failure / malfunctioning / problems with 2 engines post V1. That would not be in the book, so quotes such as the above from the book also do not apply
IMHO!
