On 1/15/2017 at 1:15pm, i was driving right outside of cookport pa when i noticed a huge completely round hole through cloud cover in the sky. there was a visible cloud trail up through the hole as if something huge just went right up through it. i stopped, took some photos, and also noticed that everything was completely silent. too silent. no sounds of any kind whatsoever. also as i began to drive off i saw a relatively large black helicopter flying right by the hole. i unfortunately didn't get a photo of the helicopter.
