As you can see, these don't have it, and I cannot locate any other airlines with it.
Can someone please explain what I am seeing? There are no other previous owners to this bird, at least that I can locate...Thanks for the help....Ryan
You can take the pup out of Alaska, but you can't take the Alaska out of the pup.

Remember this word: options... options... options...
Boeing makes airplanes and offers options to airline customers...
I never say "never has" or "always will be with" when talking of an airplane...
I never say "you are wrong"... maybe Mr. Boeing really did, or... did not...
Rick is our resident expert 757-767 here in Tech.Ops... I can only mumble about 747 whales... and will mention a few things about "fuel dump"... let me use pounds since you are from USA, some people there dont like kee-lohs...
In my 747, we have a jettison system (fuel dump) which as you know is a quick way to reduce aircraft weight in case of emergency. If you care to inform yourself about regulatory aspects of the jettison system, read FAR 25 or JAR 25 about fuel tanks and weights...
The 747 I fly has a maximum takeoff weight of 833,000 lbs, and maximum landing weight of 630,000 lbs. In case maintenance informs me that the jettison system is inoperative, I consult my MEL to read that I can takeoff, but only 6,000 lbs heavier than maximum landing weight = 636,000 lbs... Yet, what is interesting to note, if I takeoff at 833,000 lbs, and have a dire emergency requiring me to return and land immediately, probably at about 827,000 lbs or so, the aircraft can do it perfectly well, hoping the runway is long enough, because the speed will be high... All airplanes are flown by test pilots when they are first certificated, to be able to land at their maximum takeoff weight, no matter what.
I have landed a couple of times over maximum landing weight with airplanes, all they do is a "heavy landing inspection"... did not seem to be that much in it, since it was done in one hour, and signed off... maybe our MX experts will tell us about that in more technical terms...
Rick tells you that his 757 dont have jettison system, maybe some which are heavier (weight options by Mr. Boeing) require the installation of a dump system...

Early models of the 757 were not certified with a fuel dump system as there was no requirement for one. Later models provided an increased MGTOW and the FAA placed a fuel dump requirement for those models. Boeing modified the production line and this is now a customer option on all models of 757s.

Actually I think Yikes! has got it here, on closer inspection that is probably exactly what it is. In any event if such a system was installed the jettison nozzle would probably not be located so close to the fuselage but instead would be in a more outboard position as with the 767 (inboard of the outboard aileron on each wing).
I would still be interested to know if any airlines were actually forced to take the jettison option on the 757-200, or whether they all got around the regulation at the time.
I'm 99% sure that no 757 in the UK has this feature.
I used to love the smell of Jet-A in the morning...
