The craft first caught my attention by it's size and lack of noise since the Sudbury airport is so near.The object appeared to constructed in segments along it's length(130' approx).It's shape was odd in that though cylindrical it's ends were well like the ends of a bean.I was only a 1/4 mile away as it overflew Hwy 69 heading north @ 400'alt 40-60kph.It ever so slowly stopped dead, pivoted directly east and proceeded directly to the radar domes @ CAFB Falconbrige in plain sight which was part of the Pinetree line(NORAD) in those days.Somethings you never forget like just how casual this thing behaved.Not long after it was'nt visable anymore a CP airliner 4 engine turboprop came just a howling along the exact flightpath of that...that whatever it was.I'll never forget what I saw in the afternoon sun.WOW.The overall dimensions 130'long 35'wide 30'high.The construction appeared to be 9 or 10 segments of a stainless or aluminum material as it refected the sun which was on my left while the craft was on my right.No doors or openings,no lights or appendeges,no noise.It's flight was at a constant slow speed throughout the event.When it stopped and turned it happened very slowly approx 20-30 secs with no change in altitude.I was the observer and was 14yrs old.I had my first helocopter ride when I was 3yrs and had flown in many aircraft in fact I had spent that summer working at a fly in fishing camp.You Know it depresses the the Hell out me that the goverment isn't more forthwright.If a little guy like me Knows..... whats the problem.I'm presently a member of the CAF
