Saw lights like plane, but planes to not zig - zag, or make right angle turns.I was camping with my family, and friends up by Red Bridge in Mt. Baker, and a couple of times my husband, and myself saw a plane like looking lights, but it was zig - zaging around, and it moved to fast to be a plane. That was around 21, or 22:00 hours, it was hard to tell the direction it was going north the zig - zaging made it hard to tell, but later on that night about 24:00 hours I saw these lights going east then it made right angle turn north, then once again made same turn, and headed east into some clouds. Never saw it again after that. It could not have been a plane because planes don't turn sharply like that, and planes don't leave trails of gas,or whatever. You might want to picture a Z in your mind except the middle line of the Z strait instead of slanted. Oh, and it looked like it flew higher than a plane could.
