Not wishing to add anything controvercial about the sad loss I post the following in the spirit that others may learn.
I have 28 full engine failures under my belt (used to test fly for a dodgy engineer!..long story..).The only time I bent the plane was the only time I put out a mayday.The height loss was significant due to the time taken and spoilt my choices by the time I had transmitted. I note that David made a mayday .
My advice to anyone is No.1) Fly the plane. No.2)Fly the plane. No.3) Fly the plane .
Unless you are in cruise at 5000ft s*d the mayday call. No one can respond quick enough to help you anyway .
I am not making any assumtions merely trying to stop anyone making the same mistake(as me) if they find themselves in this situation.
