Ah, Yes,
Many a take off in the B-52 fortress ( and one in the KC-135
tanker) on a Hot Oklahoma day took a lot of water being injected into the
engines to give sufficient thrust to get airborne. In fact, failure of the
water injection system on certain hot days required aborting the take
off.

Well done Mr. Anderson.
That 50/50 mixture was also ingested by big radials in military power for
cooling and anti detonation.
Same for early pure jets where it was added to add mass to the exhaust flow
on take off.

I came across a study looking at ways to cool aircraft
racing engines (for the BIG iron), makes some interesting reading as they look
at EVERY way to cool a race engine including sacrificial boiling off (phase
change) of an expendable liquid as well as spray bar cooling,
etc.
