"Night Vision Another good example from the 1950s
Where Did Thermal Imaging Devices Originate From?: Thermal imaging devices were first developed for military purposes. According to Bullard Thermal
Imaging, "In the late 1950s and 1960s, Texas Instruments, Hughes Aircraft, and Honeywell developed single element detectors that scanned scenes and
produced line images. These basic detectors led to the development of modern thermal imaging." "
I'm sure it's been posted before, but night vision is not a product of UFOs, and it most certainly isn't a product of the 1950s.
The German army, and later the American army, both had primitive night vision equipment near the end of the war (around 1944). However the Germans
used it the most. Development for these systems started as early as 1936, with the first successful prototype being completed in 1939, and mounted on
a PAK 35 anti-tank gun.
Notable night vision systems in the German army were the Zielgerät 1229, an STG44 assault rifle with a large and cumbersome in-fared scope and power
backpack. They also added this system to the MG34 and MG42 machineguns.

Later on they would also mount the night vision system on the Panzerkampfwagen V Panther Ausf G (Sperber/FG 1250), and also the SDKFZ 251
Panther Ausf G (Sperber/FG 1250):
SDKFZ 251 "uhu":
The US M3 carbine with the "snooper scope", was used in limited quantities during 1945 in the Pacific.
So to say that night vision was made in the 50's, let alone by aliens, is just incorrect.
