You are correct. 1611 went down about a year earlier in the same area. If I recall correctly, some debris was collected. Maybe a landing gear strut with wheels and tires attached and other parts. The cause is a mystery also.
Aircraft 2002 totally disapeared with never a trace or communication, as far as I know. I can still recall the drone of the turboprops during climb power. I still look up when I hear turboprops climbing.
Aviation-safety.net says that they found a liferaft and the nosegear the day after 1611 crashed.
Found that when trying to find out what SHAD means.
