In Jane’s World Sailplanes and Motor Gliders by Andrew Coates (1978; Macdonalds and Jane’s Publishers. London) there is a nice photo of VV400 with number “60” under the wing and (presumably) on the tail. There is also “Empire Test Pilots School” on the nose. Photo credit is to Cyril Peckham. I hope it is OK for me to copy it and paste it below.

Yes, I’m stumped!
Laurence
Some early Schweizers had that shape fin. 1-21. I must stop guessing though.
Laurence
Maybe a Kite?
Laurence
Lovely aircraft, Eric. I agree, the nose looks wrong for a Sky: all those stringers, but the fin and rudder look Sky-like!
Laurence
Slingsby Sky
Laurence
Kaproni Bulgarski, as they say!

I don’t think the Ca309 had all that cabin glazing. Could it be the Ca306 or 308?
Laurence
Not a lack of interest: just a lack of knowledge

Identity of NASA521
I thought I had a photo of NASA521 which I took in a visit to the Smithsonian in 1986, but cannot find it. When I returned to the Smithsonian in 2008, the Kestrel was no longer on display. So I cannot help with pictures.
However maybe someone can enlighten me about the following. NASA 521 was ex XS689, 64-18262 fuselage with (according to the catalogue) XS694 wings, but it wore XS688 under the wings.
I looked back at the thread “Harriers in Museums” http://forum.keypublishing.com/showthread.php?t=51123&page=5
where it is also stated that NASA521 has XS694 wings, but why did they have XS688 on them? XS688 is stated to be in the USAF Museum.

Is that Kronfeld sitting in there?

I had noticed that, Pagen, so just wanted to be sure that we are not sticking strictly to Mr Creosote’s initial remit. I think it essential to be flexible. That was why I suggested having some “easy” ones with a few “where and when” questions when there was some doubt about the thread getting too obstruse. But see how easy my SM79 was today!
Laurence
That was quick Eric. This is one of the photos of the “graveyard” at Benghazi which Tony gave me and I published on my site. My notes there are:
Two views of an interesting SM79. This is not the usual hunchbacked bomber version, but an SM79T “Atlantici” of which three were used on the famous flight from Rome to Rio in January 1938. The wording on the fuselage is:
ALA LITTORIA S.A. LINEE ATLANTICHE
This is probably I-ALAN, used for regular flights between Italy and Brazil, mostly for mail. In May-June 1940 it was impressed in military service, still in civil markings, for flights in the Mediterranean area and to Abyssinia. On July 16 1940, en route to Abyssinia, it aborted take off at Benghazi and the undercarriage collapsed. British troops found the wreck in February 1941.
Over to you
Laurence
To add some variety, as we discussed a couple of weeks ago, even for very easy pictures:
Referring to the big one in the foreground, can you identify the type (easy), the actual aircraft (maybe a bit harder), when and where? And why was it there then?

DOWA 81 (escape plane!)
It never flew, and we said at the start of this competition that the subjects must have flown. Never mind!
I quote from post 1:
Only manned aircraft that have actually flown since 1939.
Do we still stick to this?
