Cork Screw Contrails, page 1

What type of aircraft can produce corkscrew contrails?

I haven't seen anything funny in the sky, but I sure have heard some strange rumblings -- and I know it's for real because my wife has heard them and even my dogs have been startled from their napping a couple of times over the past few weeks by strange noises from the sky.

Whatever it is, it's flying very high -- out of my eyesight at least -- and fast. And with the sound seemingly echoing around the valley, it's difficult to pinpoint the spot in the sky where this aircraft is flying.

I have noticed that there have been a number of corkscrew contrails flowing across the sky, indicating some sort of jet propulsion. Normal jet engines do not produce that kind of pattern, at least in my experience.

Must be missile as they said but I thought it was a ufo with smoke
generator,lol.

There another cool video on the same rocket. I figure disguize ufo as
rocket launches, but ufos go straight up and look like stars.

What type of aircraft can produce corkscrew contrails?

Most if not all multi engine jets can, and although rare, I've seen it happen numerous times.

One such plane is the TU-154, and I have photographic evidence:

Nice picture, eh?

Corkscrew contrails are fairly rare, but you do occasionally see them. They're probably created by airliners doing barrel rolls, I mean weird weather effects, or maybe a cross wind blowing the wingtip vortexes of the wings INTO the contrail.

As for the loud rumblings, my guess is it may be an older turbojet style jetliner flying overhead. These are MUCH louder than the typical turbofan, I should know, since 727's and 737's always fly above my head, and the 727 is MUCH louder, albeit rarer.

I also wish that people would stop bringing up the 'formation flying' thingy about contrails. It is common fact that aircraft can often fly the same route as other planes, which can appear to be going back and forth.

Well thanks for the pretty pics but I live in Nevada and this morning I woke up to a very low corkscrew contrail. What's depicted in those photos is NOT a corkscrew contrail. Those are contrails but not what is being discussed here. The aircraft that made them is triangular. I saw it once as it was ascending from Nellis. The son of a bitch was SO fast. I saw it, blinked and it was gone. Welcome to the age of Hydrogen Slush.

William One Sac.....

Are you referring to wake vortices?

These can exhibit as “corkscrew contrails”.

The winglets commonly seen on planes are designed to minimise wake vortices, thereby decreasing drag & decreasing fuel consumption.

I recently confused this with the contrails sometimes suggested to be an indication of a flight of the mooted “pulse detonation” advanced propulsion system.
