It looks pretty clearly to be an interceptor, that is a pretty radical delta wing. A single veridical with no horizontals and a visible hinge. I'm guessing a 1950s or 60s European design, probably French, but I don't know specifically.

Handley Page HP115. Early 60s-mid 70s.
Used to test low-speed handling characteristics in preparation for development of supersonic transport (i.e. Concorde)

Toby, aren't you supposed to be sleeping now? lee

One of the Thunderbirds right?

On the photographs in this thread.....
A plane's capabilities are not important as long as it looks cool as hell.

Fixed landing gear on a delta wing jet? Reminds me of a cheap Aurora model. I don't see intakes or exhaust. No markings either.
Looks like a Sci-fi prop to me.

I second Fat Frank's description of the Handley Page HP.115 use and time frame.

Is it one of the lifting bodies from the DynaSoar experiments?

We have a Winner!!!
Ding, ding, ding..... honors go to Fat Frank (yet again). Two hours fifty-nine minutes.
It is a Handley Page HP-115.
The HP-115 was built by the legendary British manufacturer Handley Page Limited at their Radlett facility. Only one example was built - XP841. It first flew in August 1961, and was part of the Concorde SST development program.
It was operated by the Royal Aircraft Establishment (RAE), which is sort of a British version of NASA. It was used for research into delta wing shapes at slow speed. The plane did have fixed landing gear, and portions of the wing were made from plywood. It was retired in 1973 after a total flying time of 500 hours and is now on display at the Fleet Air Arm Museum located in RNAS Yeovilton, Somerset, England.
The HP-115 was powered by a single Bristol Siddeley Viper BSV.9 turbojet with a minuscule 1,900 lbs of static thrust. It could power the HP-115 to a max speed of about 250 mph. The same engine, in an upgraded form, was also used in the BAe 125 Dominie (Hawker 1000), a fairly common 8 to 12 passenger business jet.
Smoke generators were used to visualize airflow and a movie camera mounted to record the vortexes.
The airfoil section was a modified bi-convex shape with a max thickness at 40% of the chord, and a delta wing with a very low aspect ratio of 75°.
Landing during initial testing in 1962.
The fixed tricycle main gear was borrowed from a Percival Prentice and the nose-gear from a Miles Aerovan. This picture shows the smoke generation gear over the front of the wing.

They flew that....
They flew that thing for 13 years? I guess that's good when you can milk data off of a test bed for that long.

Wait a minute....
My wife pointed out that a Thunderbirds movie was out about 10 years ago. So theoretically you could be about 13 and remember these.

The original Thunderbirds was a "Supermarionation" BBC TV show that aired in the 1965 to 1966 time frame. Remembered for the catch phrase....
"5, 4, 3, 2, 1: Thunderbirds Are Go!"

Well, it was designed for slow speed research.
Who knew the intent was the testing was going to proceed VERY slowly.
Must be that famous British whacky sense of humor.

Like the man said, HP.115
