Can anyone help me out with describing the why this particular shape takes place? I've been flying for 27 years and have only seen this phenomenon twice, all within a month (coincidentally).
Both photos were taken at around 35,000 feet. One was in Mississippi, the other was over New York State somewhere. Keep in mind the window is about 2.5 inches thick of laminated poly. If there are other details missing I will be more than happy describing what I can.
I understand the meteorological term, "sun dog" so don't bother with that.
Here's an interesting example of dark and light that I just took. It took me a while to figure out exactly what was going on, initially thinking it was one trail shadowing the other, but the sun is too high, and the difference far too stark for that. The explanation ended up being that the jet had two different engines.
A number of sources on the web have, since the advent and increased usage of Google Earth and other services providing satellite images, reported that a "strange" pyramid of supposedly alien origin can be see deep within the boundaries of (and each of these descriptions have been used in reference to the location) Area 51/NTS/NNSS.
To begin, let's do a little bit of disambiguation. As some of you may be aware, the term "Area 51" is often used indiscriminately and carelessly when referring to the Nevada Test Site (which is now known as the Nevada National Security Site). Area 51, whether or not the Government officially go on record to acknowledge the existence of a location with that name, does not encompass the entire NNSS, only a small part of it -- an airport and associated operations located near Groom Lake.
With respect to claims made about a mysterious/alien pyramid, the object in...
[Admin: The video that this story refers to has since been removed by the maker, George Barnes]
The Weather Channel forecaster seems to say, "it is Saturday March first and of course we are starting meteorological spraying ... ".
Here is the transcript; cleaned up as much as I can.
0:00 [inaudible] Weather Channel forecast and it is Saturday March first and
0:04 of course we are starting
0:05 meteorological spraying with a winter storm that
0:08 will be in tracking into the tri-state area beginning tomorrow afternoon
0:12 continuing right in to Monday...
So, what does this mean? Have George and I heard this wrong? "... meteorological spraying ... "
One problem I have in telling people that contrails can actually persist, and can even spread out to cover the sky, is that people tend to be suspicious of random people on the internet. So I decided to simply let 60 years of books on clouds speak for themselves.
Result: Every single book on clouds that I could find for the last 60 years says that contrails can persist for hours.
So next time some random guy on the internet tells you contrails can't persist and spread, then ask them why 70 years of books on clouds say the opposite.
A few of the forums I frequent have just started the discussion on this video and a few others like it that have appeared online recently. It was pretty roundly discounted as being something more mundane than an other worldly visitor, but as a first attempt at debunking on this site I thought I would give this rather simple one a go. (Hope I've included it in the right spot!)
Spotted high in the skies of Miami on the night of February 27th this caused a bit of a stir for some. Having done a precursory search online I found a number of things that make this seem far less unusual.
In 2008 Reuters ran an article describing that Miami was one of the first Law Enforcement agencies to start looking into the future use of UAV equipment in their ongoing battle against crime.
'Video footage taken by a Federal Express commercial airline pilot, the tankers didn't appear on the Fed-Ex aircraft avoidance system....in other words they were "Ghost Planes"
The FedEx Aircraft was on a dangerous collision heading with what appears to be two tankers. Vertical separation under 2,000 feet.
"... FedEx 5034 with request"
"... FedEx 5034 is requesting flight level '340' (34,000 feet)"
Second tanker on collision heading...
FedEx 5034 descends to 34,000 feet only to discover a third tanker at that altitude. Conclusion: tankers were operating at civilian altitude with transponder off. The control tower had no idea the Air Force tankers existed and no radar system was available to warn the FedEx pilot of danger."
This is quite laughable reading this, especially to anyone with experience in the flying world. Below we can break down each one of these statements; conclusions drawn by someone with little or no...
In a rather odd reversal of known science, the latest chemtrail theory is that modern high-bypass engines do not create contrails.
This can be easily debunked simply by a review of the scientific literature. The likelyhood that a particular engine will create a contrail is governed by the "contrail factor", and this is higher for high bypass engines - I encourage you to research this for yourself, and I give some links below.
The classic demonstration of high bypass engines producing more contrails is the study:
