First, the object had a white light on one end, and a red on the other. I say end, as assuming it was long because the lights (white and red) could be seen separated a space of about 4 to 5 747 lengths apart. I know it was one craft. Long or round football shape, I don't know first flew s by se over e Vancouver in a southerly direction. I followed it on foot it disappeared by about 5 minutes later it came back about 4 to 5 miles west of its disappearence. Flying n to nw at an northerly direction. I video on my android the same craft it moved strangely jumpy like in motion the disappeared. I don't know how to send it but I know how to Facebook it at my fb page ((name deleted)) on Facebook if that will help with sound to OK. I just wanna know what it was it flew low, about 900 feet lower than the commercial planes do when they take off or land.
