Double trouble.
First I’ve ever heard of that assessment, do you have links or support for that argument?
A statement with zero credibility without facts and breakdowns by model, conditions under which crash took place, etc.
For instance twins are regularly flown in weather that a single engine pilot would avoid. Dark nights, rain, snow, approaches at night in very low ceilings and visibility...and even a little ice.
People ask me what’s the hardest thing to fly?
I tell them the radio. Cockpit management can get way behind if you fly the radio instead of the plane.
The purpose of the second engine is to fly you to the scene of the accident.
Twins are more likely to be flown in bad weather.
