This is my second report of these Triangular shapped flying objects with red flashing lights. This second sighting compelled me to report it. My last sighting was two years ago in 2004 in New Jersey. This sighting occured in Washington, D.C. in April of 2006. I was at a friend's house and the three of us decided to go outside on the apartment balcony and smoke a cigarette. While we were out there I saw small flying aircrafts that were flashing red lights. It reminded me of my sighting two years ago and brought back memories. I realized it was the same objects. I recognized the speed of the red flashing objects. Again, my friends being very skeptical just assumed they were airplanes but not me. No way, this is the second time that these objects came around. This time in Washington, D.C. They moved the same way in all types of directions. The flying objects disappared after a short time, maybe 10 minutes. Then after that I saw other aircrafts which looked like helicopters with spot lights just like my first sighting flying around the area. We didn't stick around to see the helicopters fly around but they were gone after 30 minutes. Again I assume it is a UFO or something government related. Especially since it happened in Washington, D.C. You never really know with the government. I don't know if they were any other outside witnesses but I have done some research online and have seen some forums with other witnesses of the same event. I just decided to report this stuff since it was my second sighting of the same thing but in different states.((NUFORC Note: Witness indicates that the date of the sighting is approximate. PD))
