Just spotted this distrail. And about eight minutes later:

Don't you mean "to the right"? Or "to the left from the observer's viewpoint"? It seems pretty clear that the right edge (left on the photo) of the sunlit trail is brighter, suggesting that it is casting a shadow on the other trail.

This story seems to have had quite an inpact, unfortunately. Just the latest of many sightings...

[emphasis added] Well, at least Exley doesn't seem to be attempting to invoke chemtrails. I did wonder if that was his motive.

But WMI is one of the firms often cited as "the culprits"!

The one Murphy is holding says "Brinkmann". He bought off-brand :)

This trap would normally be connected to a rotary evaporator - you use the rotary evaporator to boil off the solvent and this trap collects the solvent, leaving whatever was dissolved in the rotavap flask. My guess is that he is going to collect a load of dust from the air using a filter or...

I'm a bit puzzled by this flask. It is a dry ice condenser trap. I don't see how it would be any use for trying to collect particulates from the air. Available on eBay: http://www.ebay.com/itm/Brinkman-dry-ice-vacuum-trap-condenser-ball-reservoir-dewar-with-bottom-valve-/191669714207? This...

Same thing is happening for me, on Chrome and on iOS Safari.

This is the data from Herstmonceux (about 60 miles southeast) for 00Z today, which is about 18 hours before the photo was taken. FL450 is equivalent to 150 millibars. This sounding would suggest the highest humidity (in the region above 300mb) is at around the 190 millibar level. Here is...

And here is a photo taken approximately 10 minutes after the one above, showing the trail persistence (it appears to have barely moved in 10 minutes, I think because the upper-level wind is almost parallel to the trail).

Here are the FR24 screenshots. And confirmation of the Gulfstream registration from Planefinder.net, which tends to have more information for private aircraft than FR24 does.

Looking out of my window around sunset this evening I noticed a succession of planes lining up from the west, all with short contrails except one which was leaving a lengthy persistent trail. I thought it would make quite a good illustration of how "adjacent" flights can be at very different...

I took a series of photos that are very similar to that video from a flight back in March: Again the apparent change in direction is just down to the aircraft I was on flying roughly perpendicular to that one, while the aircraft on the right is flying roughly parallel to my flight.

Day 2 and he points at a contrail and "estimates" that it is at 8,000 to 10,000 feet: "definitely within our range". You would think that when he flies up there and it's still not seemingly getting any closer he would start to question his ideas, but no...

One of the highest contrails I've seen for a while: a Gulfstream at just under 45,000 feet. (And a sundog.) And some more trails and shadows a few minutes later. Edit: Planefinder had more info on the Gulfstream. It was en route from Pittsburgh to Geneva. It's owned by PPG Industries, a...

A nice pair of sundogs here this evening.

And he's in a Piper Saratoga II HP, which has a ceiling of 20,000 feet. I guarantee he got nowhere near those contrails.

Incidentally, a little biographical snippet... I've just been doing a bit of digging and I'm pretty certain that the U. V. Bogaerde who wrote that first letter is one Ulric Van den Bogaerde, the father of Derek Van den Bogaerde — better known as Dirk Bogarde! The family had a home in Clayton...

Well, I have a paid subscription to the Gale database which includes The Times.There's no free online access. But public libraries ought to have them on microfiche. Those are all from the letters page, and all from August 1944. I don't think I made a note of the publication dates (I took those...
