On June 17 a pilot filmed another aircraft coming straight at him just a 1000 feet below him leaving a beautiful contrail behind. Just amazingly beautiful. (www.20min.ch) 更多...
When this popped up on an Austin TV station Facebook page the chemtrail nuts came flying out of the door jamb.
As it was I even had to correct the "journalist" who posted the piece then added the chemtrail BS at at the end. I gave a basic explanation of physics and how all that is actually ice crystals that would soon turn back into vapor. I also explained how that was a pretty dramatic effect indicating the relative humidity was considerably higher than normal at that altitude.
Most of those idiots couldn't comprehend the basic physics of vapor to ice if their own ass was wet and had frozen at -80°.
Tim - Sadly, I think you are right. (I wonder where some people get this stuff! At least they have an imagination, but wow, is it in the wrong direction!)
My first thought, too, Bill. If I was the FAA or AOPA I'd pass this one around as a "Look at this and see what you could fly into on a departure or arrival." Or in flight.
A few years back I was in my C-T210 passing over Philly at about 7,000'. Beautiful clear Wx. All of a sudden I got WHACKED! Hard. With seat-belt on tight, my head still hit the overhead. So hard that if forced sound to come from my throat while I was talking to ATC and they asked what was wrong. Scared the crap out of me. Actually looked around to see if all the plane was still where it should be.
And then I got hit again!!! Same thing.
Controller told me it was probably wake turbulence from a 737 passing left to right in front of me minutes before, at about 9,000'. Second hit was the second (left side) engine.
Yes, a perpendicular crossing is just as you described and without belts on you could easily be knocked out and/or severely injured. I'm sure its just a misstatement but the hits actually come from the wingtip vortices.
When I was a youngster there was a TV show titled "Contrails". It was one of the things that attracted me to flying early in life There are daze I wish I'd never seen it. Back then the DC-3 was a big airplane and the 6 was a huge airplane until you compared it to the B29.
Très bon! I recall seeing the "screw" pattern in the prop washes while following a Convair 440 Metropolitan at LAG going to the active runway just after a rain shower. Neat!
Awesome video. The soundtrack added a sense of being there too but, as a PAX, I hate that voice-distorting constant white sound. Will science ever provide better sound-shielding? (Maybe moot with out-of-atmosphere trans-global travel.)
I am always amazed that people explain this to be some sort of chemical disbursement conspiracy theories, clearly air moisture content has a lot to do with the phenomena.
I'm always attracted to the pre and WWII news reels and movies centered in Eastern Europe with Spit fires swarming through twisted smoke trails and bomber groups on their way to locate and blast away targets feeding the war effort from the other side As many of the comments here attest, contrails are beautiful to behold and I add have been around longer than our ability to separate and manufacture chemicals. I can't swear to it, but I think the chemtrails thing got stared through a late night after night radio show as did "War of the Worlds" some years ago. History is redundant.
I can believe a "short term" experiment, but this stuff as been carrying on for years and years thanks to Art Bell et al. Now it's the 'goment' trying to control the weather. It really is quite a sight.
I Hope all is well with you. I haven't swapped comments with you in a while.
Seen this movie from the front seats and the biggest thing I get out of it is how close RVSM has put airplanes together. The ones below you don't count!
Just curious. Below don't count? I'd think the ones above wouldn't count either. It's the ones that are dead on ....
Many of those who would find the video frightening think nothing of doing 65 with only a double line between you and the texter going the the opposite direction.
It is a 1000' advertised, even though we calibrate the systems on a regular basis and keep up enhanced maintenance it some cases it is less than that 1000 feet....
Or when someone screws up and incorrectly sets there A/P in correctly or bumps the yolk and the a/p changes from ALT Hold to pitch and no one is flying the plane! (IE Human Error)
Oh yes.. I remember TCAS in its infantcie - We were the pilot airline back in the very late 80's and early 90's. I remember installing Beta .9 software and we would replace the TCAS Processors every day upgrading to new software.. back then you had 4 antenna's and not just 2. You had one omni and 1 directional antenna on the top and bottom. Now the Directional is on the top and the omni is on the bottom. Instead of the info being on the EICAS Screens it was in cased in the VSI as colored (RED or GREEN) LED's.... I have watched this system grow and become so much more reliable over the years and personally think that is the single biggest safety device installed on a/c todate!.... (IMHO)
This video is beautiful and amazing but if every car and truck driving past your home did the same at ground level, you would be upset. Yes it is only water vapor, but it does not completely disperse and disappear. What should be clear blue skies become milky white. Aircraft contrails are causing a change in normal cloud formation.
This is a fact that no one wants to hear.
As soon as you complain that your blue sky is no longer, you are deemed a chemtrail conspiracy theorist nut job.
Chemtrail or Contrail, it is causing effects noticeable to people on the ground.
I respectfully suggest that it would be in the airlines political interest to acknowledge contrails in high traffic areas are causing noticeable visual effects and have flight plans adjusted to minimize this.
https://science-edu.larc.nasa.gov/contrail-edu/science.php What adjustments would you see as reasonable and practicable to mitigate these visual effects, and what outcome would you expect to see? How would you solve the problem?
The Hudson river lander, an Airbus, they deployed the front slides. I spoke with a Westjet attendant and she told me on the Boeing they have to disarm the front bags in a water landing. They would block the doorway! Would the front of the 737 sit lower on the water. That seems like a CofG thing?
I disagree with that... I do not see that would be any different. The operation is the same. The nose is out of the water, the door opens, the raft deploys from the same location in much the same manor!
Not sure.... I know I have deployed those slides as well (during functional testing) and I do not see where they would block the door unless the nose was almost under water and that would be the same for Airbus as well... Maybe boeing is considering it a sunken boat already!
