That's a beauty. Straight lines, a holepunch (possibly several), ripples. I can see a lot of chemtrail sites getting excited over that one...

@Cloudspotter your charts show why I saw pretty much the opposite of you on Sunday here in the south. Lots of trails in the morning when I went out on my bike: Then by mid-afternoon the sky was back to clear blue as the humid air moved away and we got the drier air you had earlier. (No pics...

Yes, as both I and @Trailspotter noticed, yesterday was a very good day for long-distance trail watching here in the UK. A nice cold clear arctic airmass gave really good visibility. I don't think I'll be rivalling 200 miles though, as there's a house and trees immediately to my west blocking...

My daughter wouldn't have been too impressed. "I know your dinner is burnt but daddy is taking photos of planes again..." And actually I came back upstairs two or three minutes later and it was no longer visible. I think it had passed into shadow - my photo was taken 14 minutes after local...

A nice mirror image of my avatar pic at at sunset tonight. This is a Fedex cargo flight, an MD11.

It's just gone sunset here and a few minutes ago I managed to get a photo of a plane about 125 miles away. It's British Airways flight 95 which was heading away from me towards Canada, so I had a great view of the sunlit contrail all the way. At the time I took this photo, the plane had gone...

Yes as Belfrey says, the augmented reality view may help. I think a lot of chemtrail believers (well, a lot of the general public, I guess) have a poor sense of scale when it comes to planes. They see a big contrail up in the sky and think it must be within a mile or two, and often low down to...

I would say that is just the trails from one four-engined jet. Compare this pic I took the other day: That is a Lufthansa A340.

I'm not a pilot but I believe that is the rotating beacon which is illuminated while the engines are running? https://cpteg.wordpress.com/tag/rotating-beacon/

This is why I love this site!

Another problem is that just about any sample of air or water that you take anywhere is going to have some trace amount of metal in it (especially if it's sampled from an aeroplane which is basically a big aluminium tube!) And when you consider that samples like this, which contains about 7...

This one came up in the "related videos" and it's an even bigger contrail (not meaning to steal your thunder!) (Added bonus: you can also see the shadow of the contrail being created by the plane it is filmed from.)

See my post earlier in this thread: https://www.metabunk.org/threads/photos-of-planes-and-contrails-that-you-took-yourself.1487/page-9#post-122713 This trail: Separated into this:

Neil, it might be wise to edit those images to remove Herndon's address and email address?

Same flight number. If this is a daily flight at the same time of day, get yourself out there on a hiking trip before sunset gets too much later!

Yes, it was early in the morning and there was an inversion, with cloud cover on the plains and clear air above. I don't have any photos to prove it unfortunately, as I only had a wide-angle lens and it didn't show up. Here's a pic from another trip, though, showing the layers of distance haze...

For a scientific answer to this question, let's assume an observer at sea level and a contrail at 40,000 feet (towards the upper bounds of most commercial traffic). This is effectively the same as calculating the distance to the (sea level) horizon for an observer standing on a 40,000ft...

I tried following a plane on FR24 and taking photos until I could no longer see it. The problem I have is that surrounding houses block the horizon - not a problem Mick has apparently! The planes usually disappear behind a rooftop when still clearly visible. The furthest I've managed to get a...

This was the effect I was referring to on Google Street View. Example from the Czech Republic here. The green banding in the sky is very similar to the effect in the contrail pics, but there are also other coloured bands.

A few from the archives. These are from a round-the-world trip I took in 2002-2003. Contrails above California. Taken when I was driving from San Francisco to LA, but I have no idea where exactly! Possibly somewhere on I-5? March 30, 2003: The same day and similar location, a sundog which...
