I’m an engineer and consider myself well grounded and pragmatic but a number of years ago while sailing across Lake Erie, I saw similar lights as described here high in the night sky. They moved in radical, obtuse patterns unlike any conventional aircraft and then would hover for minutes at a time then simply disappear. They had blinking red, white and green lights, from various sections on the aircraft.
About three years ago, I saw similar lights to what I described near Leamington, Ontario. I don’t just jump to conclusions easily, but these two events have convinced me there is something more out there than what we are being told and allowed to know. They were just too different from any aircraft modern humans have.
