We set up our hummingbird feeder as we usually do every night and this time we seen what appears to be a triangular light traveling in the clouds. we used a go pro in order to record this. the go pro was set up to take a picture every 0.5 seconds. the battery for the gopro lasts three hours. the entire video in time lapse turns out to be 10 minutes. so we calculated the video clip that we sent you with the light traveling to take about 2 to 3 minutes, it appears to be traveling fast however in relationship to the clouds. it also appears whatever it was it looks to be in some kind of stealth mode.
