Ok everybody...
I was shooting pictures in the afternoon (02/23/2007) about 2 miles west of KORL and I happend to get these two winners that the photo screeners are going to be killing eachother to accept.
NOT!!!!!
One I'm pretty sure is an E-2
(Feel free to use as a desktop if you can stand the grain)
and the other one is an F-15
Now I obviously cropped the hell out of this shot, but that's due to the nature of the question. Now keep in mind it was Shot with my 300 MM maxed out. The Eagle was moving so fast I'm stunned I didn't hear a boom after it had passed. That being said though..
Now the trail it's leaving was with it from horizon to horizon. The question is: Why does it look more like it's dumping fuel out of the starboard wing then creating a contrail (Chemtrail )?

Well im not no genius but... maybe for practice... or maybe just because they didnt need that fuel... maybe they needed less weight to land at a certain place... thats just my wild guesses to this...

Quoting TedTAce (Reply 2): What I'm concerned about is 85 views, 1 reply, and no one saying I'm delusional for thinking it's something other then a contrail.
You forget you're not in civ-av!!
I don't think it's contrail because it appears to becoming from the right wing with no symmetrical contrail from the left. The left wing appears to have an external fuel tank. Since they like to fly external fuel tanks symmetically (one on the left and one on the right) it stands to reason there's another tank on the right wing.
Since whatever is venting seems to be coming from about the location on the right wing where a external tank would be I think it safe to assume it's fuel going overboard.
My guess is the F-15 has declared an IFE (InFlight Emergency) for a fuel system problem and is keeping it high to reduce fuel burn until a runway landing at the desired location is assured.
I work on an AFB and IFEs are pretty much a daily occurence and very seldom end up on the front page of the paper.
You didn't happen to see a tanker nearby did you?
edit: For those smarter on the F-15 than I: Is there a fuel vent at the after end of the external tank or its hard point that would help explain Teds Mystery?

Quoting ZANL188 (Reply 5): I was thinking if the F-15 had just hit the tanker he might be full up and venting for that reason.
The F-15 would have reported her fuel load to the Boom Master either prior to docking or once connected. As such, the tanker would have sent a load below her maximum tankage minus her remaining fuel, so it is unlikely she was "over-filled".
Who? I've spent lots of time working with tanker crews and have never heard of this guy. You're thinking of the Boom or Boom Operator.
Aircraft get overfilled and vent after refueling so it's not unlikely, just improbable in my view since Ted reported the venting continued for sometime.

From what I can see in the nice photo from the rear- the tanks look a little (but NOT the same as) an F/A-18 drop tank. They do have dump valves on them, and you can just about make it out at the rear of the tank in the picture ZANL188 posted.
As to why- you got me!!! The "dumping 'cuz I got a problem" seems the most resonable, but what's a Navy guy know about the AirForce...
Classic planes, Classic trains, and Studebakers~~ what else is there???

That Eagle is dumping/venting. The F-15 has a dump and vent system tied into each other (which makes for one hell of a troubleshooting nightmare) on the right wing tip. Since you said that it had made the trail from horizon to horizon, I think its actually dumping as venting doesn't happen for very long unless a manifold is cracked. Its carrying 2 bags and I don't see a centerline, probably just eliminating some excess weight before landing. Plenty of 15's dump if they come back earlier than expected...like ZAN said for IFE's and whatnot.
Since he's pretty high up too, the JP8 its dumping won't reach the ground below as it evaporates at altitude within minutes.

No, receivers don't report how much fuel they have on board (unless they are BINGO), nor does the tanker crew really care how much they have. We pump them to the scheduled offload, or full tanks, which ever comes first. When he gets full tanks, the air refueling system disconnects, and stops the pumps (just like at the gas station when you fill your car with gas and it stops when it is full).
He could have recently refueled, or has a valve stuck open somewhere. Either way, the fuel is coming from the vent system, and he does not know it yet. If he knew about it, he would stop it. Remember, in an F-15, you cannot see behind the wing.

That was highly likely an F-15 from the 125th FW at JAX....they have several of them at Homestead at any given time for the Alert Det, and they ferry them from one end of the state from the other every so often. If not maybe an Eglin or Tyndall bird far from home.
I don't recall a vent on the droptanks...just your standard drop tanks.

He probably just tanked with AR pumps on the tanker to make sure his drops got filled inflight so probably hanged on the boom longer than needed to make sure . I'v'e seen F-16's on the boom and you can easily tell when they are full, they vent out from every vent . Plus if it was hot on the ground where he left and sat for awhile the fuel will expand it has to go somewhere (don't know if F-15's have surge tanks like big boeings) and is slowly leaving the acft as the tanks pressurize going up in altitude. Back in the day on KC-135A's and Buffs it was a preflight task to drain the the surge tanks before flight, on a tanker if you got more than 5 gallons with no end in sight it was a write up with and entry in the forms. you had a valve problem in the crossfeed mainfold that was not closing completely.

The vents are located on the aft end of the pylons for F-15 externals.

Does your wife make you take off your clothes in the garage or back yard before she allows you in the house, I rather have JP-8 in the armpits than Skydrol in the eyes or on your manhood.

Hah, yeah. I used to have to strip down in the garage before coming in, and even after 3 showers STILL smell like fuel.
Quoting Venus6971 (Reply 19): Skydrol in the eyes or on your manhood
Agreed. Though I have had JP-8 in the "nether regions" and it doesn't feel good either. I'm sure with Skydrol, it would just all fall off!

Quoting DeltaGuy (Reply 21): the only thing I'm in danger of is some PET or something silly like that
Pet IS dangerous! I almost fell off a C-130 wing after lubing up a tank probe because of PET! To think I almost lost my life to an over-rated tub of Vaseline...
Don't you engine shop guys use some gnarly anti-sieze thats pretty carcinogenic?
Quoting Venus6971 (Reply 22): but if you are ever working with Skydrol and have to use the head wash your hands first before you go, trust me on this
