V shaped stealth aircraftThe aircraft had 4 lights, one in the apex of the V shape and the other on the front and side wings. It was moving slowly and then turned abruptly, you could not hear anything, so it was in stealth mode or using some sort of quiet engine. After turning it flew in the same direction and eventually the lights went out and we lost sight of it. The craft itself looked metallic grey and the light in the apex was red while the other ones were regular light. I could make out the V shape because there was nothing connecting the wings together which is why I found it odd in the first place.
