Finally - and this was news to me when I first heard it: B707-100 "water wagons" used all their water tankage on TO, and the water tank(s) was purged dry during climb, to prevent freezup at altitude. Do other aircraft do this as well, or do you retain unused w/m mix and just top up on the next leg?
