Before the Harrier and F-35, they had this thing in the 50s.
R/C Model of Lockheed Salmon XFV-1
Ryan X-13A-RY Vertijet Jet Tail-sitter
Vertijet flight testing
from http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19750022036_1975022036.pdf
here is a concept of using an F-16 (which has 1:1 thrust at low weights) but keeping cockpit horizontal.

Interesting, thanks Hesham.
From the text, this model just seems to be testing the pivoting forebody as a possible way around the shortcomings of the X-13 Vertijet. The tailed-delta appears to have won out over the 'least mod' version of the F-16.
The 3-view (Fig.3) on page 19 shows more details of the airframe, reaction controls, etc. Attached is a more compact, reorganized version of that Figure.
BTW, for anyone interested in the LTV XC-142A, there's a drawing of the 'free flight' wind tunnel testing of that V/STOL aircraft on page 25.

Right Apophenia , it seems that this model haves nothing
to do with the F-16...
to do with the F-16...

There was also F-18like model as well. I am sure that I posted the photo somewhere on the forum, but cant find currently where.

Looks like a GD take on the Grumman "Nutcracker" concept.

They just took spare model to make the tests.

The model used in the investigation was a modified version of an existing research model generally representative of current fighter configurations.

Well, Matej is right, but I couldn't find it, too.
Here it's again, from Aviation Week 1975, the F-16 was used
as basis, as well as the F-17.

Thanks Jens. Interesting to see the different pivot points chosen for the two models.
The same F-16 photos were reproduced in the NASA pdf but your AW&ST versions are of much better quality.

It was just a two page article, here's the other page:
(we already had it here : http://www.secretprojects.co.uk/forum/index.php/topic,2140.15.html,
"F-16" and "tailsitter" were the "passwords"
)

Would they be designed as an ejection module rather than seat ??
Sorry, can't remember which production aircraft had this facility-- Well, except for the Valkyrie, with its pods.....

Really too much of: dymodel time: 2008-4-6 14:29 German crazy, this is not the Bernhard molecules fantasy, but the design of the Focke-Wulf Triebflugel, if the war be extended for a few years, perhaps into combat . Such a wing for the rotor, in truth, it is feasible, but demanding and fuselage connected to slip ring / so waving wing to meet the enemy, like flying monsters of Juchui psychological vulnerability of the enemy, not U-turn before fleeing? After the war, the Focke-Wulf did not give up the tail sitter concept, which can be short, jet FW 860 the tail sitter's program / stent support on the ground in a strange takeoff roll the aircraft, and then stand suddenly erected (this Figure in the erection, do not Lenovo Oh!), and then, like the tail sitter vertical takeoff and landing sequence in turn, Lockheed XFV-1 / the Convair XFY-1 The Pogo the Convair XFY-1 in level flight into the jet era, Tail, Sitter also times, Ryan developed a jet engine, the X-13 / Vertijet can also take off from the tilt rail Tail, sitter as a manned fighter is already an outdated concept, but for no man-machine, or a good Boeing Heliwing is an example of Tail, sitter not only in the United States a lot of interest in France will also be given a great deal of attention. SNECMA is the manufacture of aircraft engines, SNECMA in the 1950s and 1960s also involved in a VTOL aircraft, the tail sitter machine launch Coleoptere series. Tail sitter Coleoptere and the U.S. Navy is also different, not only the jet engine, but also a rare circular wing (annular wing). The ring-wing can be seen as round, up and down the wings, and between the upper and lower wings with winglets to connect. In the case of the same wingspan, the ring-wing can produce higher than the level of wing lift. The annular wing did not roll stability and roll which angles are the same right wing, cabin may have been confused. Of course, the ring-wing aerodynamic analysis and manufacturing is too much trouble for horizontal take-off, landing gear must be unusually high, but for the tail sitter, which is not a problem. Development of SNACMA the Coleoptere to C450, when the tail-sitter landing difficult problem has become very prominent, the French Air Force's operational requirements have changed, only it is no longer sufficient for VTOL performance falls far short of the tail sitter and conventional fighters, the French Air Force interest is also volatile. Very interested in the French concept of the Tail, SITTER, SNECMA design a strange ring wing the C450 Coleoptere research machine / C450 take-off angle can clearly see the ring-wing, in a sense, this is the wingtip wing toward the extreme, or the wings of the biplane complete with ring connected to with French Tail, SITTER is very serious, had considered the Tail, Sitter concept JCM88 fighter

What about to turn modern conventional fighter jet, like PAK-FA into tailsitter?
