He is the author of more than books and has written more than magazine articles and short stories, and several plays, all primarily for teenagers.
Oliver Smith A remarkable video has emerged of a Boeing Dreamliner spewing out a thick cloud of vapour as it flies over Russia. The clip is bound to fan the flames of conspiracy on some of the more incredulous online forums.
So persistent is the chemtrail theory that it has been discussed on radio talk shows, raised by politicians, while US government agencies report calls from irate citizens demanding an explanation. The trails which arouse the most suspicion are those that remain visible for a long time, dispersing into cirrus-like cloud formations, or those from multiple aircraft which form a persistent noughts-and-crosses-style grid over a large area.
Proponents of the conspiracy theory offer a variety of explanations.
It is an attempt to control global warming, according to some, while others cite far more sinister goals, such as human population control, psychological manipulation, and military weapons testing. The trails, it is claimed, are to blame for health problems and respiratory illness.
It is an attempt to control global warming, according to some; others cite human population control, psychological manipulation, and military weapons testing These claims took root in the Nineties, with the publication of a US Air Force research paper about weather modification.
The truth Governments and scientific institutions have, of course, dismissed the theories, and insist those vapour trails which persist for longer than usual, or disperse to cover a wide area, are just normal contrails.
The variety of contrails seen in the sky is due to atmospheric conditions and altitude, they say, while grid-like contrails are merely a result of the large number of planes that travel along the same well-worn flight lanes. Patrick Smith, a US pilot, dismisses the conspiracy theory in his book about air travel, Cockpit Confidential.
Water vapour, strange as it might sound, is a byproduct of the combustion within jet engines, which is where the humidity comes from.
Whether a contrail forms is contingent on altitude and the ambient atmospheric makeup — mainly temperature and something known as vapour pressure. It clearly didn't work.
The EPA reissued the document as recently as Of these emittants, only water vapour is necessary for contrail formation. Newly formed ice particles will continue to grow in size by taking water from the surrounding atmosphere. The resulting line-shaped contrail extends for large distances behind an aircraft.
Persistent contrails can last for hours while growing to several kilometers in width and to meters in height. Contrails spread because of air turbulence created by the passage of aircraft, differences in wind speed along the flight track, and possibly through effects of solar heating.
There are a couple of other interesting facts about contrails. Military aircraft will sometimes fly at a particular altitude to avoid producing them, and therefore evade detection. Also, when a plane is travelling towards an observer on the ground, it may emit a contrail that appears to be vertical.
Six other air travel conspiracy theories 1. Oxygen masks are there to keep you docile Brad Pitt is to blame for this one. In the film Fight Club, his character Tyler Durden says the following: Oxygen gets you high. In a catastrophic emergency, you're taking giant panicked breaths.
Suddenly you become euphoric, docile. You accept your fate. It's all right here [points at an emergency instruction manual on a plane]. Emergency water landing — miles an hour.
Blank faces, calm as Hindu cows.I also teach fourth grade and I have been using this theme in my room for the last two years. You have some great things planned. A couple of things I can add are.I have my students sitting in groups.
The stars of "Avengers: Infinity War" are one, big happy family in parody of classic '70s sitcom. Here's the way they all became the "Marvel Bunch.".
So, once upon a time there is ('is', not 'was', luckily the guy is still around) a prolific Japanese creator known as GooGoo64 whose technical deficiencies made them a subject of this one video series I used to do a long time ago.
