What you have to remember is, that the 3 rocket engines only have to propel 11 percent of the mass of the Top Secret TR-3B. The engines are reportedly built by Rockwell. Many sightings of triangular UFOs are not alien vehicles but the top secret TR-3B

The above Video was recorded in florida
One of the main features in this video that points to “terrestrial craft” is that it appears to have a blinking safety light, conversely, an item that points to something other than a TR3B is that it doesn’t appear to have the purported rocket engines on each tip of the triangle said to maintain 11 percent of the lift, unless of course this is an improved model since original reports detailing it’s operating principles were outed back in the early to mid nineties.
And of course three more items point to really advanced technology, the fact that it is hovering stationary, it was reported silent and it rotates at a central point.
