Water Take-Offs

[The Legendary Spitfire]

Did this by accident at first, flew low over the Channel (as in 5 feet or so) and landed in the water but managed to take-off again. However, in a propellor plane the prop stops quite quickly.
The rocket plane is impossible to get back into the sky after touching the water.
Withe 262 jet however, the jets stop but the momentum gained by pointing slightly down regains the speed needed to climb easily higher than the height you lost.

Useful or not?
Pretend to die by crashing then astonish your enemy by flying straight back up and killing them!
