Talk about a wicked scream!  The "old" KC-135's used to use water injection on take-off in Riyadh in the 80's; and they if the wind was from the south they didn't run out of water until they were right over our hotel!  No sleeping through that noise! :)

(In comparison; where I'm currently at, the KC-10's carryabout three times the fuel (as the 135's) and are really quiet)
