    Flight SQ26. Looks like there was an Aer Lingus plane 8,000ft almost directly below it at the time.

    Noticed these 2 contrails yesterday here in "flyover" country...the older one really spreading laterally with the prevailing upper winds. The younger one happened to be a NASA flight from Palmdale, CA to Hamburg, Germany.

    Novcontrails. Novcontrails2. FLTRDR24.

    Regular vapour gap, as they say over the pond. :)

    I am afraid I was not paying much attention, and missed that. The Flight SQ26 trail stood out and half waked me up.

    That's the SOFIA Telescope. I'm close enough to Palmdale, that I see it every once in a while. SOPHIA9817.

    Another "corkscrew shaped" contrail. Presumably an illusion due to the pendules being blown one way and then the other, rather than the whole trail actually being twisted.

    A lot going on in this sky- multiple contrails criss-crossing but what really caught my eye was the Kelvin wave cloud...was so much cooler looking 5 minutes before I got my "camera"...(and in person- sorry for the crappy pic quality)

    A nice long fall streak over Bakersfield, California. 3:40 pm, January 1. This was a 3 frame shot using the panorama setting. DSCF1050b.

    A possible candidate. After having watched the direction of it's drift and time it took to deteriorate. AS3497 flying from Burbank to San Jose reached it's cruising altitude about the time it was alongside the I-5 sign just south of Wheeler Ridge, it maintained an altitude of 26,000 ft., it began it's descent just a minute or 2 after I stopped the playback to take the screen capture, just south of Blackwell's corner.

    I contacted Meteorologis Miles Muzio of KBAK Channel 29 TV here in Bakersfield, ran my photo and the plane track by him. He provided me with a satellite loop of the fallstreak. The full loop can be viewed here: http://rammb-slider.cira.colostate.edu/?sat=goes-16&sec=full_disk&x=4190&y=4076&z=5&im=12&ts=1&st=20180101230038&et=20180102000038&speed=130&motion=loop&map=1&lat=0&p[0]=16&opacity[0]=1&hidden[0]=0&pause=20180102214539&slider=-1&hide_controls=0&mouse_draw=0&s=rammb-slider

    Am I looking at the right streak? It doesn't seem to match the flight path. Or is it the long trail to the right of the curved streak?

    How long does it take for a fallstreak to take shape? There's a third one that forms between the second and 3rd frame. FR24 showed AS3497 started it's descent at about 23:08 or 23:09. It shouldn't have been in the first frame, now that you mention it.

    The Sun was about 3 minutes from sunset and I got this photo. In the photo you can clearly see the shadow of the 3 birds and the contrail on the upper cloud layer (I do not remember seeing the shadow maybe because I was looking at another plane which was in the South and I just randomly snapped this picture without properly looking in the viewfinder), guess it should go in debunking of flat Earth.

    Recovery 252.

    Bird shadows get a thumbs up. (vultures?)

    this relates to https://www.metabunk.org/posts/216735/

    Singapore SQ297 bird back over my head 630 am 11/1/18 on its way to Christchurch New Zealand & this time i was able to show the RH at 250hpa was ideal for exhaust contrails.. Im hoping now to catch & show it above me but on day that does not support contrails.

    It's a bit odd that FR24 app on your mobile does not have different icons for different plane types.

    Aircraft icon setting is on Generic rather than Realistic
