Here my guess:
- It appears stationary as it is travelling towards the camera and very far away.
- It isn't apparent in the visible spectrum because of cloud/haze between it and the camera.
- The plume appears as it passes through a layer of cloud and heats the moisture therein.
- Applejinx 10y agoAbsolutely. It's a twin engined something, and we're seeing the heat signature. May not even be an unusual aircraft.
- heatButNoRadar 10y agoHow come no radar signature. Is that not unusual for aircraft, or are most aircraft radar absorbing?
- hindsightbias 10y agoMost civilian ATC radars are 'Secondary' radars which depend on cooperative transponders on all aircraft. If you turn your transponder off, the system doesn't work. US ATC uses 'Primary' radars as backup for locating aircraft that don't have transponders or don't have them on. Militaries use Primary radars for most of their activities. Other articles don't provide distinction on what type of radar was used.
- libraryatnight 10y agoI've experienced this a few times driving near the airport. It's really mind blowing until the highway changes direction a bit and the illusion is ruined.
- kowdermeister 10y agoSeeing that blog post this is probably the case.
- madaxe_again 10y agoI think that's sound - and the "plumes" from the object would make sense as turbulence from its passage seen head-on. I'd love to have a straightforward explanation to this mystery too, which was a few months before this was filmed, and has been an itch in my mind for the intervening years. http://www.pbase.com/flying_dutchman/pacific_eruption http://www.pbase.com/flying_dutchman/pacific_eruption
