"In my aircraft I am out of gliding range of land for 90 seconds."
A very efficient aircraft flying the shortest route then.
A typical PA28 will manage 1.75 nm per 1,000 feet, flown perfectly.
The shortest crossing possible is around 26 nm, so I suspect if you do the maths and fly at 3,000 feet you are out of glide range for rather longer.
"you had better hope the aircraft floats."
"Most aircraft float,"
Ah well, that's settled then.
