“Riddle me this: How is it that the large, silent, hovering triangular object witnessed by people with otherwise unimpeachable credentials, can suddenly propel itself upwards or towards the horizon at such high astronomical speeds and out of sight in a mere instant without leaving the tell-tale sonic boom?”
Well, one answer could be that it isn’t a solid object at all. Maybe it’s just a hologram, a projection. Then it wouldn’t be bothered by air resistance, the laws of momentum, the sound barrier, or any of that stuff.
I never say “never”. However, the incident that I would offer is the gigantic triangular shaped UFO that travelled from southern Indianna, through southern Illinois and into Missouri before darting off. It was followed by and viewed by many state and local police departments on the road. To project that large of a hologram over that distance would have required an awful lot of support equipment, power and a mighty tall tower for projection to pull that off.
Implausable, but I’m not saying it’s impossible.
