UFO crashes just outside Roswell New Mexico 1947. US Army move in to clear the wreckage and bodies etc, and hand it over to scientists at Area 51 for study.That was 62 years ago, do you think that maybe some of the technology we take for granted today may have been a result of research into whatever crashed at Roswell?

Definitely,
Look, we are still driving a basic Combustion Engine which was invented 110 yrs ago, same engine, no matter it is in latest Corvette or Bonnie & Clyde's Ford V8.
OTOH look at meteoric rise of computer technology, do I need to say more?
We are inventing stuff with exponential speed. Where does the know-how come from when it is in baby steps in other areas?
