    Wow, excellent. I hadn't known about Graham Hancock.

  It's the Dolphins. So long and thanks for all the fish!

    They are cylindrical, grey, without apparent means of aerial propulsion, and prone to interfering with ultrasonic sensors... Most dolphins are smaller than a compact car, but I bet they would break apart upon impact with a frozen sea after dropping out of the sky. This might be the correct answer.

      Yeah, but they travel in pods of 42.
