Well i have to say lots of interesting stuff there. No surprises really, just the same old same old. With reference to blocking people we have a very clear and consistent policy on our page, which is if genuine people ask genuine questions, no matter how contrary they are, we will leave those comments there and try and respond as best we can, and that even includes some flippant ridicule. We dont allow offensive material obviously and delete it. So to answer accusations of blocking members of this website, of course we do, because what they post is neither genuine nor constructive, and their identities are not real either, so they fall very much within our 'delete and ban' policy. Most intelligent people now realise what this forum is, and it aims, now so my comments will not come as a big surprise to most.
So, explanations out of the way, let's address some interesting images you guys have posted shall we. 3rd trails? Care to explain?
You all claim that ''contrails' are the result of moisture in the exhaust gases freezing very quickly and forming ice crystals. Tenuous at best, but more importantly where does the moisture for the 3rd trail come from. A KC10, and i have no idea i have to admit, what a KC10 is, but it certainly seems to have only 2 engines?
I look forward with some excitement to you responses
Hi Ian, I am glad you stopped by. I am a KC-10 instructor flight engineer with over 3500 hours of flight time. In my previous job I was an F15C/D aircraft mechanic, working on the Pratt & Whitney F100-PW-100 low bypass turbofan engines. Since then the engines have been upgraded to the more efficient and F100-PW-220.
I took the time to drop by your site the other day, and couldn't help but notice the new "modification" you had discovered on the Airbus A320, that you believed was a modified aerosol delivery system. You had been asking for schematics showing what indeed this "modification" actually was. It seems we never got to discuss it further, since the Lufthansa A320 manual I posted, showing that these tubes are in fact pylon drains was swiftly removed from your site, and I was blocked, claiming that pylon drains "don't exist", the manuals were photoshopped and that planes costing $100 million "do not leak anything".
Since that topic is for the other thread, I would like to formally invite you to stop by and explain how a heavy aircraft with thousands of moving parts to include internal engine bearings and hundreds of feet of hydraulic, fuel, pneumatic and water plumbing cannot leak. I would be glad to even show you the picture from boeing.com that shows engine drains on their products. I flew last night and during my preflight walk around I happened to notice that my beloved KC-10 also has these pylon drains. I would be more than happy to hear your explanation without anyone being censored, blocked or deleted after presenting documented facts. I can tell you that my engine leaks a lot:
And because the hydraulics can and will leak, I have this checklist in my publications:
One of the most significant DC-10 accidents in history was United 232, which had a catastrophic loss of all 3 hydraulic systems after a #2 engine (tail engine) failure. Had it not been for the actions of the legendary Captain Al Haynes, who managed to land the aircraft with just the use of the engine throttles, everyone on board would have been killed that day. It was that incident that prompted a modification of the hydraulic system, and this checklist.
The main reason for this post is the fact that I noticed this post from you earlier.
I would be glad to explain. The KC-10 has three engines, since it is a modified DC-10 with an air refueling boom and drogue assembly, used to refuel other aircraft in the air. Here is a picture from FlightAware of us taking off in Scotland:
The pictures you have posted of the "Tail Sprayers" are all of 2 engine airliners. If you take a look at the shots of a KC-10 from below, you will see the #2 engine on the tail producing a contrail just as the wing engines are, with the contrail forming some distance behind the exhaust of the General Electric CF6-50C2 high bypass turbofan engines. (73% fan, 27% core). It is similar to its bigger sister the MD-11.
I am excited as well to hear your response sir!
