I know exactly what you are talking about, although I never knew it was white ? :think:

Hey Tony
Nice FLIR film

Couple of thoughts (and I may be talking out my derriere) Looks to me that there are two clear shock cones and as far as I know
757s dont have afterburner ---- Im not sure about the airspace - but my feeling its two aircraft (prehaps F16s) in formation
I was curious about the "rolling motion" that Paul noted , until I watched to pairs of F16s departing Nellis up to the Range about an hour ago.

After taking off and in the climb I noticed that the wingman rolls around the leader coming back up on his left wing...My assumption was it was to check external stores on the aircraft...so maybe thats the odd motion that Paul saw. the only thing that doesnt make sense is the 180KIAS thats awfully slow for a Falcon even in climb. But thats impressive footage

BTW Aurora is now passe - the scram jet UAV is alot smaller and operates from Crystal Springs.

The 180 knots was just me Leif, suggesting that Tony's dog wasn't at Vr when he filmed it

I see what you mean now about the reheat, and on thinking about it that makes sense. Baring in mind this camera is tuned to turn dog poo white, is it possible that these were not reheat, but just normal yet engines. Bare with me here, I've been giving this some thought.... probably all wrong.

From about 20 seconds on in the clip, the wider angle shows the ground and some heat sources there showing as white. Now given that "the thing" looks to be several miles away, I wonder what the temperature it thinks the "white lights" are? Say for argument sake 30 - 60 celcius? So if someone was to throttle back and the exhaust temp was to drop by 30 - 60 celcius, the "white lights" on the camera shot would disappear?

there is a place halfway though the video where it dims and what ever is washed out by the brightness of the two heat sources becomes visible.
can somebody catch that frame and post it. I don't have the software to do it. :doho:

also it disappears into the clouds I think. it doesn't vanish.

On the thermal camera I play with in the day job the white to black range is scaled to fit the temperature range of the scene, so with a large temp range there's not a lot of contrast and vice versa.
When we were in the hold for RIAT last year I tracked the F-22 do it's demo and whenever it went it to afterburner it pretty much saturated the display for a few seconds while the display recalibrated, however if I'd put manual gain control on prior to it engaging the 'burner then once it entered I'd just have seen a bright white blob the whole time. Going by that I'd say the camera was in a fixed gain mode (the background scenery stays the same after the two blobs disappear) which would mean any heat source above the top of the calibrated range would be bright white and assuming it's heating the air around it that would be too.

Maybe its' the same thing(s) as took out a wind generator in Lincolnshire earlier this week???

Well this has generated some good ideas etc.
Ok this is what I think it is, I am pretty sure of this I am willing to wager my mortgage house wife four dogs and a nagging daughter...so if I lose I still win
We have the FLIR Star Safire 3 camera fitted and its damn good when it works correctly its the puppies privates. I normally set it to auto on the gain side of things as this covers most things, the pod is fitted with a spotter scope, low light camera, day camera, HD camera and the FLIR, it cost about £750,000!
I was scanning East from the Western Side of the Midlands somewhere between Wolverhampton and Dudley. I before changing to a close lens had it on wide when I picked up the heat scource. (the camera goes in FLIR mode from wide, medium near, super near and ultra near fov) I started to record when I went into near fov, when you look at the video you see the heat scource to the left of the city (Birmingham) it starts a right turn and goes into cloud. The heat is from the wing mounted engines of an airliner and the heat trace ie the spread from the engines is pretty normal to see in FLIR mode. I think the distnace about 20 or more miles stopped the camera locking properly onto the body of the aircraft hence no visual of the fuselage, odd thing is the APU should have been glowing??
So I still think its an airliner doing a normal take off from R33 then initiating a standard right turn... or maybe I lost 9 minutes and was "probed" sadly I can remember nothing of it

I will when next on duty get some daytime shots of stuff in and out of BHX on thermal, its quite interesting to see the detail these cameras can show!

I doubt if anyone will take you up on that one mate
