The Engines did not fail.
There were no mechanical failures.
All this arguing about Rules, why not about argue about properly flying the machine?
Violating a Rule does not harm you but not flying the machine surely does.
Get back to 60 Knots at 35 feet and 90 Knots at 125 feet then a nose low attitude of 35 Degrees and a Rate of Descent of 2400 FPM that was increasing.
Ask yourselves how and why all that happened on a very foggy night with visibility said to be "Tens of Meters" .
Was that indicative of an appropriate Take Off Profile?
Does that suggest there may have been more Visibility and a thinner layer of Fog than is being considered by everyone?
Did that bit of Hovering clear out a small area of Fog and the Crew be able to see up?
