I'm NOT good at military aircraft, but I think the top photo is an f-100 the 'thud' from the vietnam era.?? and I even close?
.. the bottom one I really don't know, but I'll guess a surveilance aircraft of some type.. early on in the spy-in-the-sky days.
I saw a very strange airplane in Connecticut about 25 years ago.. It was [I pretty sure] a military prototype or one-off for High-altitude photography... It was a big powered glider...typical glider layout,, huge long wings, had the single center landing gear, with 'coaster wheels' at the wing tips, a large military type canopy . It had a camera rack with a glass floor, and an ejection seat framework. The plane was powered by a geared Lycoming TGIO 540, with a huge propeller, the prop looked like it should be on a Convair 580. the prop blades were about 8" wide at the tips, and obviously were meant to spin very slow.
The exhaust from the engine was ducted down the side of the fuselage, in a double walled duct, with air vents in and out, and the exhaust pointed sideways, and exited the ductwork quite a ways back, after it would have had lots of time to cool, and give off a minimal infra-red heat signature..
I really wish I had had a camera with me, but I didn't and don't have any photos at all.. I wonder if the plane is still at that little airfield in central CT...
