CorvAircraft> detonation...not a good thing!

[Dave Morris "BigD"]

The F4U Corsair throttle has a safety wire across the last 3/8 inch 
of throttle travel, marked "War Emergency Power".  Shove the throttle 
all the way forward, break the wire, and it kicks in a water 
injection system that is "for combat use only" and assists in 
preventing detonation.

I remember in the 70's on TV in Albuquerque those aftermarket water 
injection systems were all the rage.  Wonder if that had to do with 
high altitude and the low octane fuel they use there to prevent vapor lock.
