Dear Prof Steve

Do UFO really exists OR Can we classify them as Science Fiction Objects ?.

If i am not wrong, There were also some movies also made on Flying Saucers regarding aliens Landing from UFO.

Another Interesting point to be noted is UFO Shape. i.e. flat bottomed saucer, convex on one side.

Answer
Hello Prashant,

There have been many occasions that I saw a flying object that I couldn't identify. Many of them have been birds, I could tell that much, but I couldn't identify the species. Other times I could see that it was a plane but I didn't know the manufacturer of model number. So I have seen ufo's, but I don't believe I've seen a UFO.

Yes there have been many movies about aliens visiting the Earth. And the special effects teams seem to favor a saucer shape.

Have a good day,
Steve

Expertise

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.

Experience

I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.
