It may be a strange 1 in a million chances but today I was flying my P3 at a local lake, taking pictures and and everything else we do. It was still daylight at around 7pm. My phantom was around 350ft altitude when my wife said hey would you look at that!!! What is that she said. I began to look it was a large plan flashing some extremely bright (looking) lights. Not red and green ones like you see but just a normal light. It was way way up there. I dropped my phantom back to the ground and a minute or so later the plane turns the lights off and continues on!?!? What the heck!?
