This one was interesting... I was asked a question my fellow founding coder Angus Mc Dermott in our last Podcast "What is Truly Out There.." about anti-gravity propulsion... I didn't have a good answer so I deep dived down the rabbit hole to gain a better understanding and ended up finding Otis Carr.. He is an interesting man, who potentially built operating flying saucers using electromagnetic anti-gravity propulsion... Did he actually do it..?  Have a listen and make your own mind up... Enjoy.
