Chemtrails, feit of fictie? deel 4

quote:

Formed at 12,000 and the weather caught us. Couldn't climb fast enough to keep out of it. So we took off on our own to avoid any planes in the clouds. Six of our wing men went home when they became separated from us. We left England on our own and headed across France for Strassbourg. The contrails were dense, persistent - really hard to even see our own squadron. Our Air Leader really got worried about us being by ourselves. Jack and I had to argue like the devil before he saw the light on the bomb run. He wanted to bomb in group formation with just anyone. We wanted to take our 7 plane squadron in by ourselves. On account of Whitt is really an expert on PFF (couldn't bomb Micro-H - too far from the beacons). Then - on the bomb run the bombsight froze up, due to lack of precautions by our visiting bombardier, and Whitt dropped the bombs, aimed PFF at the center of Mannheim.

Yes, we certainly did. Contrails were so thick that they became clouds. We often said that we created weather over Europe. They would persist for many hours, maybe days. We flew a different route coming back than going in partly to avoid the contrail clouds that we created. There are some pictures of contrails on my web site - none of these are shown to be very heavy but there were time when we were near the end of the bomber stream and the contrails were so dense that it was no dfferent than flying in clouds. A thousand or more
planes (4000 internal combustion engines) can make a lot of contrail at 25000 feet or more.

quote:

As you've assumed, the bomber crews as well as our fighter escort saw contrails about every day even though an effort was made to avoid them. As was often said, they represented large fingers pointing to the bombers. Obviously of assistance to the enemy fighters who could spot us at a considerable distance.

The nature of the contrails was such that they required certain atmospheric conditions to form. thus, they were principally affected by altitude. At the pre-mission briefings, they typically advised us of the altitude that the formation of contrails could be expected with an effort made to avoid that particular altitude. More often than not though, we did in fact make contrails indicating that their information was faulty or that flying at that altitude couldn't be avoided. We in B-24s typically bombed from about 22,000 feet while the B-17s, which could fly higher, bombed from around 27,000, particularly at tough targets where higher was better in an effort to avoid the flak as much as possible.

My recollection is that the contrails persisted for some time. While I don't recall timing them, I would guess that they could be seen for fifteen minutes or more. At times, Germany appeared to be almost covered by contrails as far as you could see. Essentially creating a cloud layer which could possibly persist for hours I suppose. The bombers' in more or less straight lines, the fighters', usually above us, more random as they criss crossed or circled. A common sight was the escorts dropping their tanks and heading off after the bad guys.

Grappig... niks geloven van graancirkels, dat ligt daar maar en moet wel door mensenhanden gemaakt zijn.
Maar een paar wolken in de lucht zien, en er van overtuigd zijn dat het roze olifantjes zijn.. maw, zeker weten dat daar meer achter zit dan condensstrepen, creert door vliegtuigen die op hoge hoogte vliegen.
Grappig.

Klopt, maar hier komt dus Global dimming om de hoek kijken. Het effect van het broeikaseffect is op dit moment minimaal hierdoor en wordt dus onderschat of zelfs als een mythe afgedaan.
