From an earlier thread of mine:
Saab 105XT, SE-XBZ 2nd prototype, c/n 105-2 built in 1964 as SE-502. This is the aircraft which belly-landed at Farnborough in 1972, very embarrassing! However there was so little damage it flew again the next day. It went to the Flygvapenmuseum at Linköping in 1982 and was loaned to Svedinos in 2003.
This aircraft can still (2008) be seen at Svedinos, which is the car and aircraft museum at Ugglarp, located an hour south (by car) from Gothenburg.
Could the donor have been the subject of the hilarious account on pages 55-58 of this story?
I hope the link works!
I agree wholeheartedly with Kev35.
Pardon my ignorance, but I fail to see what benefit would be gained by a further partition in this Forum. What I expect to see when surfing this site is commentary and information on historic aircraft, regardless of whether they are military or civil – it’s all HISTORY, for heaven’s sake!
I am an active member of several Fora on the Web, and have enough jumping around from one to another already!
Just to add my two-pennorth, I feel there are enough sub-forums already and would not personally like to see yet another. My interests cover both civil and military (and there are quite a few aircraft that have “crossed the boundary”, e.g. Constellation) so I am against that idea.
It is true that many of the Forum members who were here a couple of years ago have decamped elsewhere, but I hope that newer members will eventually show their mettle. One thing that I am very glad to see disappear is the venom (and I don’t mean de Havilland’s) that used to occasionally pop up.
Straining my memory back about 20 years to the time when I was writing instruction manuals for infra-red equipment, there were different levels of gray for different temperature bands, with the absolute hottest being white. Nowadays colours are often used instead, but the principle is the same, so the bands could be at 5 degrees, 10 degrees, 20 degrees and so on. Therefore if using a 10 degree band, everything between (say) 11 degrees and 19 degrees wuld have the same shade of gray (or the same colour). Similarly everything between 21 degrees and 29 degrees would have the next lighter shade of gray (or the next colour).
Depending on the setting determined for the highest temperature (usually white on a gray scale) a person in front of a hot fire could well become invisible, i.e. if the max. temperature setting was for body heat.
The technology has without doubt improved immensely over the last 20 years, but the basic laws of physics remain the same!
I now agree with you, Chumpy, about the Vulture, comparing it with the Vulture head-on view on page 125. In fact Sqn Ldr MacLaren is pictured on the next page of the said book, but I am hopeless at recognising faces so I couldn’t say if that is the same person in the second posted picture, or either of the two others who made the trip, as they are all in the Putnam’s picture.
The Imperial Japanese Navy ordered two Vikings in 1922, and it certainly looks very much like a Viking.
“They were test flown by Major H. G. Brackley off the carrier Hosho in March 1933 on acceptance trials, having been ordered as fleet spotters . . .” (Putnam’s Vickers book, page 119)
For those who may wonder how this feat of prestidigitation was accomplished, there is a small menu bar at the top right of the Dassault page, where you can choose English or French versions.
Part of my job is to create such translated pages, by the way.
Don’t believe everything you read on the web!
The SR-71 was only ever used or equipped for reconnaissance, and the picture from jayhawk shows the M(Mother)-21/D(Daughter)-21 combination. The D-21 was meant to be an unmanned drone reconnaissance vehicle with recoverable hatch containing a camera, to get around the fact that the US had promised not to overfly China any more.
Although Kelly Johnson had some discussions with the USAF about bombing capability for the SR-71, mainly in an attempt to prolong production of the SR-71, it came to nothing. There was therefore never any “strike” capability, despite the name.
I commend the Jay Miller book “Lockheed’s Skunk Works – the first fifty years” which contains comprehensive details and photographs of all the A-12 and SR-71 projects, and much more besides. (ISBN 0-942548-56-6)
Seafire development
There was a fully comprehensive history of the Seafire in Captain Eric “Winkle Brown’s “Spitfires with Sea-legs”, an article in the October 1978 “Air International” which by coincidence I have just read. Here is an abbreviated extract that throws some light on the problems encountered:
After the unexpectedly high incidence of deck-landing accidents during the first day of Operation Avalanche, in advance of the next series of coastal landings called Operation Gragoon, Jeffrey Quill was made an RNVR Lt-Cdr by the 5th Sea Lord and sent to practice deck landing in the Seafire and report back, since Captain Brown was deemed too experienced in deck landing by this time to be able to give a clear indication of the difficulties that an average pilot could encounter.
Asa test pilot, Jeffrey was the ideal choice, and the report he submitted on 29 February 1944 included four main observations:
(1) Pilots had to be trained to employ a curved approach;
(2) Multi-ejector type exhaust manifolds should be fitted to all Seafires and the pilots trained to land with their heads out of the cockpit and looking along the port side of the engine cowling;
(3) the Seafire had inherent poor speed controllability;
(4) the Seafire lacked the necessary robustness for carrier landings, but the fitting of a sting-type hook would probably reduce the accident rate.
As his article goes on to relate, eventually these measures were implemented, and in the end the Seafire was developed into a fully capable deck landing aircraft, especially with the Griffon engine.
I repeat, this is the best description of the evolution of the Seafire that I have ever read, and it would be well worth reprinting, if that is possible, for the current generation of readers.
Oops, sorry, I was looking at M.69 Marathon, can’t remember where I got the 1949 from. However my database does have the May 19, 1946 date for the M.60 Marathon.
This makes the Marathon precede the Ambassador in a way, although taking into account the probable differences in design periods, I would guess that the Ambassador began design first.
Airspeed Ambassador first flight of prototype July 10, 1947
Miles Marathon first flight 1949 (does anyone have the precise date)?
No problem for me here in Sweden (although it’s 5 a.m. and I should be in bed!)
1. Finalise my divorce in France which has so far taken 6 years and cost me a fortune in (French) lawyers’ fees.
2. Regain half my life savings which are tied up in the apartment (in France) which the b***** will not leave, in flagrant disregard of a French court order.
3. Get a new image-stabilised long lens for my Canon 350D (or perhaps a new camera . . . again!).
4. Take another overseas trip to try out my new lens (or camera) and practice, practice, practice panning!
5. Enjoy free or discounted travel as I officially become a pensioner later in the year.
