I heard a story once.
A unit of Ghurkas was going to be airdropped into a risky behind the lines operation.
The comander of the op informed the Ghurka's leaer that they would be dropped from a very low altitude <500ft.
The Ghurka talked with his men, came back and said they felt they would be safer jumping from maybe 50".
The commander sxplained that 50' feet would not allow enough time for the parachutes to open.
To which the Ghurka replied, Ahh, we didn't realize we'd be using parachutes.
You can't be too rich, too thin, or have too much firepower.
