We seen 3 ships in a triangle pattern that hovered over us very close to the ground.Me, 3 of my friends (age 18), and the father of one of my friends (age 39) were working on four wheelers in the shop. We noticed lights in the sky coming towards the shop that were flying low. The lights stopped just over us. It was hard to see the shape of the craft because the lights were so bright. It was 3 crafts, 5 lights on each in a triangle pattern and close enough to the ground that the lights shined to the ground.They hovered over us for a very short time and then all lights went off. About 5 seconds later the lights came back on. The crafts changed position each in line behind the next and took off. Moving at a very high rate of speed. There is a tree line about a mile north and it took all off about 2 seconds from a dead stop for the crafts to disappear behind the trees.There was no noise, no sound from a motor, just complete silence. Even as they took off we heard nothing.
