3 orange lights, 3-4 minute duration, then vanish.I walked outside and saw 3 orange lights in a row, flying as if they were planes coming into land. After a couple minutes I realized there wasn't an airport close and that there were no flashing lights. I lived next to BWI Airport for 20 years so I'm aware of what planes look like at night. They were orange with no flashing. After another minute the top light stayed still, the middle light moved over right and the bottom moved upwards and they formed a triangle. I stood outside for 3-4 minutes watching this happen, until I needed to grab someone. I went inside and grabbed someone very quickly and went back outside, it only took 10 seconds of my sight off the lights. When I was back outside they were gone. That's it, just like that.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
