The pilots claiming to have seen the large underwater craft and the tic-tac saw it visually only. The radar on their planes could not pick it up. They watched it for 5 mins and engaged it ( flew at it aggressively, they did not have active weapons). That is where they saw it acting erratically and stopping and starting as if you threw a ping pong ball inside an invisible box before “noticing” them, and mirroring their movements as fravor flew down in a large circle, before cutting across the circle at the tic-tac. It then flew past them as “incredible” speed.
That would be quite the laser pointer to make that scene.
