I used to be a jet engine mechanic in the AF. We had water injection
systems on both the KC-135 tanker and B-52 bomber. Both engines had spray
bars in the inlet to provide the water. It worked by making the air more
dense, giving better performance. The trick is that it has to be sprayed in
small dropletts, not poured in. Also had to use distilled water to prevent
build up of deposits which eventually reduce flow. Worked very well in most
cases, especially on those very hot days on Guam with a full load.

So did some aircraft. There was also an add-on water injection system
available from Edelbrock in the 70s, to help high compression car engines
run on lower octane fuel.
One of my friends years ago was a flight engineer for AA. That was when
they
had the "Flagship Planes". The DC6 co-pilots job was to stick a small
American flag outside and above his window both on landing and takeoff.
The paying public was always to see an American flag flying over the DC6
when it arrived and departed the gate.
My friend was involved in water injection experiments AA were doing to get
more power from the airplane-I imagine to compete with TWA's Constellation.
One morning they were taking off to take the very first flight test data.
Fortunately,they were flying from a little used field (except for
maintenance).
The plan was to take off, and he was to, on command, start adding
increasing
amounts of water injection into all four engines. Something bad happened,
and as they were climbing out, there was a huge misunderstanding and he
added
full water injection into all four engines, all of which immediately
stopped!
The co-pilot yelled to the pilot "What do you want to do now chief?"
The very busy pilot yelled back "Break out the flag, we're about to land!"
(My friend said the pilot declared a "Mayday", made a very tight 180 and
landed downwind on the runway, No damage, no injuries.)
