It's a shame.  What could anyone do for the pilot except watch?

The real estate business must be good up here.
The plane was registered to a company in Rochester NY and was going to Naples Fl.
The plane involved was a Socata TBM700 which became unresponsive to ATC.
The escorting F15s state the windows were frosted over and the pilot appeared to be slumped over the yoke. They had break off over/before Cuba. The plane crashed just north of Jamaica. It appears there were 3 on board.
I'll read the investigation report when it comes out. I'd like to know whether the cabin pressure monitor was operative, but, may never know.
