so i was reading a post about ufos, saying a disc shape would be very unstable

So I figured a disc shaped spacecraft could appear stationary yet have a electron accelerator around the inside of craft creating that spin to stabilize.

Still require propulsion though to lift off. I think this is why I use go dream about a bicycle taking off and racing around the earth, within 10seconds to reappear on the horizon.

Everyone knows that alien ships are computer controlled so they don't have to be stable.

I'll five star you anyway.

The disk shape UFO's have the older style non-integrated propulsion systems.

One system was used to move the craft up-down, another system was used to bend time slightly to move the craft forward.


These systems are ultra reliable, however in combat situations the non-integrated systems was an Achilles heel.

An integrated propulsion system uses a common device that both systems harvest simultaneously and are always in phase.

A lot of the older systems are still in use and can be identified by a circular shaped hull, however some craft aren't able to bend time and use the main propulsion for vertical and directional travel.

if your only potential problem with the whole "OMG!!! the aliens!!" horse shit is circular vehicles, you really should give up sci-fi flicks. no self respecting life form capable of crossing the interstellar void would have any interest in us. we suck that bad, really.

You assume that we cannot product craft that can travel outside of this atmosphere.
