What kind of airplanes were these?

Ok, so i was moving recently and i had stuff in a storage shed, and it was like 2 am and i lived in a rural area in Pennsylvania, United states and i heard this airplane so i looked up and it was a pretty big plane with red plain and blue lights, so pretty much red white and blue, but the odd thing was for a couple seconds i could see a verry faint Pitch black plane right infront of it, it looked like a stealth bomber, and it was weird because it was like 1:30 - 2 in the morning. Does anyone have any ideas what they were?
