I am entering this as todays date and time because I do not remember when these events happened even though they have been over the past two years. This same series of events has occured 3 times at twilight. I was driving into Burnside Industrial park drving along Burnside Drive when I look up and at a distance I see a black object that has 3 white lights in a triagle formation. Normally when I see an object in the sky that I do not recigonize I look for the marker lights (e.g. the red flasher on the botom side of most aircraft). I did not see any on these objects. One time I did notice a faint steady red light in the centre of one object. What realy makes these stand out is the fact they are going very slow, and they seem to make the same FLAT left hand turn in about the same area. Most aircraft except for helicopters will bank to make a turn. These do not they make a flat aproximetly 45 degree angle left hand turn. As I stated before I have seen this three times always at twilight and strangly enough appearing to follow the same course. The next time I spot one of these I will write a report with the exact day and time.((NUFORC Note: Date is approximate. PD))
