    Contrails versus humidity: a timelapse project

    Nice pics. Again that fits perfectly with the humidity charts.

    Debunked: Clifford Carnicom's "Contrail Physics"

    But contrails are closer to the sun!!! (By about 0.000007%...)

    What might these three planes be?

    A lot? Doesn't FlightRadar24's €1.99 a month Premium package give access? Surely a paid government shill can stretch to that! ;) Edit: never mind, I see that still only gives 30 days of playback.

    Contrails versus humidity: a timelapse project

    May 4. A good example, this one: Mostly cloudless sky in the early morning, with slowly increasing fair-weather cumulus. A couple of bits of cirrus/aged contrails drift in from the southwest around 09:45 (08:45Z, 0:26 in video), but the main arrival is about 11:15 (10:15Z, 0:39 in video)...

    Contrails versus humidity: a timelapse project

    May 3. An overcast start, with the cloud starting to break from about 12:30 (11:30Z). Plenty of cumulus cloud through the afternoon, and into the evening, but deep blue sky in between, with no visible contrails right through to the end of the day. RH is above 90% at the start of the day...

    Contrails versus humidity: a timelapse project

    May 2. Not much to see here, totally overcast, but included for the sake of completeness: It does illustrate that even with low humidity at 300mb, it can still be totally overcast, with high humidity at lower levels. In this case the humidity at 300mb at 12Z is only about 30%, but at 700mb...

    Contrails versus humidity: a timelapse project

    There is also an overnight timelapse for the night of April 30/May 1, which shows the abrupt change in conditions: The night starts out very clear, with several planes passing by on the east-west transatlantic flight path but not leaving any trails. Then almost on the stroke of midnight...

    Contrails versus humidity: a timelapse project

    And here is May 1: Lots of very persistent spreading contrails in the morning, hidden at times by more general cirrus. Contrails continue through the afternoon, hidden by more general cloud cover but still obvious at eg 16:00 (1:24 in video). High cloud begins to break up about 18:00 (1:42...

    Contrails versus humidity: a timelapse project

    I was planning to start with May 1, but the conditions on April 30 provided a nice contrast to May 1, so I will start there. Here is the timelapse video: A mixed day, with plenty of cloud and the odd shower, but the sky in between the clouds is deep blue with virtually no visible contrails...

    Contrails versus humidity: a timelapse project

    This is something I've been meaning to do for a while: a daily record of the contrails (or lack of contrails) in the sky, in a known location, compared to a daily record of the atmospheric conditions in that location, specifically the relative humidity at typical aircraft cruising height. I'm...

    Debunked: Chang'e-2 photos of Alien Base on Moon [Hoax]

    This is a very good point. That Lunar Orbiter photo was frame 3085: http://www.lpi.usra.edu/resources/lunarorbiter/frame/?3085 The principal point location is: Latitude: 4.94° Longitude: -0.34° You can put these coordinates into the LROC Quickmap viewer: http://target.lroc.asu.edu/q3/ and...

    Patrick Roddie - San Francisco, California, Rainwater sample

    And not only that, but barium at a concentration of 0.16 parts per million (that's 0.000016%)! What mechanism does he think can do that?

    Debunked: Chang'e-2 photos of Alien Base on Moon [Hoax]

    The image is not a picture from the Chinese orbiter at all. It is an edited version of a photo from NASA's Lunar Orbiter 3, taken in February 1967! Original pic: https://www.metabunk.org/data/MetaMirrorCache/ed4ec513292b374ec0a022c92d4d40b0.jpg The area in question is at the back right of...

    Why do People Remember the Sky Being Bluer In the Past?

    I found this set on Flickr with a lot of photos from London Heathrow airport in the 1980s. I was looking to see if there were any good contrail shots. There aren't, but it's noticeable just how white/grey the sky is in a lot of the pictures even on "sunny" days. Certainly not the blue skies of...

    Photos of Planes and Contrails (That you took yourself)

    By coincidence I first encountered this plane just the other day. I was on the train and saw a big contrail heading off into the sunset. Checked FR24 and it turned out to be the Dreamlifter on its way across the Atlantic from the Boeing factory in Italy. No photo of the plane/contrail as it was...

    Debunked: Look-Up.org.uk Alleged "spray pipes" on A-320 are Pylon Drains

    Notice the upload date, too. More than two years before Look-up first made their claims about the pylon drains.

    Chemtrail Fleet - Peter A. Kirby

    Agreed. Considering this is such a central part of the chemtrail my this, why does nobody have any videos of it happening? I've seen lots of photos of planes flying parallel to existing contrails, as you'd expect with normal flight behaviour, but NONE of the same plane turning back to create a...

    Pre 1995 Persistent Contrail Archive

    The "pre-9/11" pool on Flickr has quite a few. 1985. I think these are contrails:

    Pre 1995 Persistent Contrail Archive

    One from my mother's photo album that I've been meaning to add. Taken on Lundy, an island off the southwest of England, in 1986. I've boosted the contrast, as the sky was very washed out. (This was taken on a Disc camera, which weren't known for their image quality!)

    Chemtrail Fleet - Peter A. Kirby

    I notice that entire article contains not one photo of one of these alleged chemtrail tankers, just the endlessly recycled David Dees image of the KLM Boeing 747* with retrofitted skulls, and a couple of Evergreen pics. Where is his "proof" of these planes spraying in the sky? (*Original here...
