I thought they were just regular flights though. It was not Voodoo1, it was not flying yesterday. http://flightaware.com/live/flight/VOODOO1 I did see some parallel contrails in the morning, they did not last long though.

They looked very much like the picture at the top of this page taken near Portland, Or. I saw them from approx. the same angle as I saw the VooDoo1 tracks on 11/20/08. The trails I saw yesterday were even more impressive than the 11/20/08 circles. I'm wondering if this was a repeat of the VooDoo1 avionics tester. Robust contrails today as well which correlate with the water vapor maps as we get ready for an approaching low. -Bryan Hi Uncinus,

Looks more like 3 6s you know, 666, the mark of the devil...I have no clue why abouve london, and pray its nothing bad I have just seen 3 above london…hmm.

But it's not their call - it depends on the traffic. Yeah, the airlines certainly don’t want to be put in holding patterns – very expensive. But it’s not their call – it depends on the traffic.

So leaving from PIT or CLE and circling for 20 minutes 5 mins NE of PIT is wasteful... I guess it can be blamed on the immense amount of air traffic and limited number of runways that can support large passenger jets? That 24 hour loop of nation wide air traffic is still crazy to watch after 20 times... there's a few hundred, maybe a thousand planes at one point and it's pretty dark... 5AM or so and the next few hours you can watch the outline of the USA form, particularly the eastern coast, and fill in the central parts to a lesser degree I can understand that, but they raise ticket prices partially based on fuel prices rising… So leaving from PIT or CLE and circling for 20 minutes 5 mins NE of PIT is wasteful… I guess it can be blamed on the immense amount of air traffic and limited number of runways that can support large passenger jets?

Planes have to arrive in their destination in a specific order. Doing a 360 (a circle) is something that ATC tells you to do - it's not a racetrack hold, as those are at specific points, it's just a way of moving you back 2 minutes (after a 360, which takes 2 minutes, you end up in the exact same point (well, except for wind, close enough), and it's a lot easier to do that a racetrack).

But one was from PIT and one from CLE so why not hold them on the ground instead of burning 20 mins of fuel circling? Or were they doing something more sinister 300 miles from their destination? ;-p awe… 9:54 and there’s only 2 left ;-( They were all going to LGA which I think is New York Laguadia?

(usually a bit longer, as they are very dense).
