The Tristar, DC-8, 707 and VC-10 could also do it. It is a very expensive way of transporting engines around the globe. The prefered method now is to three engine ferry the aircraft back home. (Or two engine ferry the tri-jets!). Before you do this you have to do boroscope inspections and power assurance checks on the remaining “good” engines . Also the aircraft has to be flown by a specialy rated crew and it’s got to be empty of course!
I was involved with doing a forth pod on a Tristar years back and I can tell you it was a back breaking, awkward and long job!.
Oh, one other thing,not all aircraft were capable of doing it as it was an option fitted during build. This cost a lot of money and the aircraft were hevier than the other’s in the fleet.

Wasn’t there some rumour about subsides from the World Health Organization too?. I think I remember reading in “Flight” that the Canadians were contributing umpteen million dollars to the WHO. The WHO were giving Brazil the same amount of aid and the Brazilian government were giving Embraer EXACTLY THE SAME AMMOUNT in subsidies!!!. Perhaps that is why?. I also know people who look after the 145’s and they recon they are C**P!

There were the remains of one at Beirut international back in the late 1970’s. Don’t know if there still there and you are welcome to go and look!!!!!

I personaly think that the big problem would be BAe. They are not keen on old aircraft, just look at the resistance they have put up over the Vulcan/Lightning/Buccaneer. Actualy they are not that keen on new aircraft either but if you want a site for a retail park….!
The main spars for PA474 were repaired with parts left over from the shack program. So those bit are not thick on the ground either. It does make me wonder about the long tearm futures of both Lancasters

Didn’t some chap in the States build a 1/3 scale replica years back, powered by two VeeDub’s?.
Or perhaps we could have the helicopter version instead!

There are two types of toilet systems in general use on passenger jets.
The first one is the older type and it consists of a tank in the toilet compartment right below were you are sitting!. This is emptied by attaching the “Honey waggon” to a dump point on the outside of the aircraft reasonably close to the toilet area. Once attached a small lever is operated to open the outside vale and then a “T” handle is pulled to open the dump valve that is generaly mounted inside the toilet tank. The waste is then sucked out of the aircraft. once emptied the tank is flushed, the dump valve is closed, the tank is filled wilth fluid the hose is removed and the outer valve is shut!. This system has no overflow. The natural expansion of the level in the tank allowed for, BUT if it’s not emptied if will overflow INTO THE CABIN!!!!!
The second type is called the vacuum toilet. This has a large tank(s) at the rear of the aircraft and the “waste” is sucked through to them by pipes by a vacuum . That system is emptied in the above maner BUT there is no fluid placed abord the aircraft specificaly for the toilet system. The toilets use water from the aircrafts water system for the flush. This system again has no overflow but it does have a vent for create the vacuum in the air and to allow the vacuum made on the ground by the toilet “blowers” to exhaust through. If there is a failure in the filter system in the top of the tanks you can get waste blown out of hear if the tank get over full.
The stories you here from time to time about blocks of blue ice falling through peoples roofs occure when you get a leaking outer valve seal. It is a problem that most airlines take very seriously, especialy if they operate 737-3/4/500’s as a big block of ice falling from the front toilet servicing piont will go straight down the front of number two engine!!!!.

Mr Ross, is there any chance you could send me the ISBN of Testing colours?
Both my brother and I are Ex R.A.E. apprentices. I have a copy of the book and he want’s one too!!.
I was in “A shed” the day XE531 crashed. It was on the way to Holm-on-spalding moor for some testing by Bae. I for some reason decided to ignore it going and do some home work instead!. The accident report said that a compressor disc had burst, cutting the aircraft in two and at that hight there was only one thing the pilots could do!!!
Years later I actualy bumped into the pilot who at the time was flying for B.A.
