Stupid aliens. No wonder they spend all their time sticking probes into our back ends.
Here's more from the YouTube description:
Sighting around 9:20pm Washington County Pennsylvania. Object moving Southeast to Northwest. At first the object only has 2 lights on it. Then one other light slowly dims on to the right. Which then splits into 2 smaller lights. Then a few more lights turn on. I have no idea what shape this object was but the sighting was astonishing! No sound from the aircraft. Definitely a fake plane. Temperature 78 degrees. Clear sky.
