Debris from Tuesday's Reaper crash has been recovered along the shoreline of Lake Ontario.
Sights of debris from the 174th Attack Wing MQ-9 Reaper were reported to local authorities Thursday, and the investigation into the crash is ongoing.
Air Combat Command officials have convened a Safety Investigation Board to determine the cause of the crash and recommend ways to prevent similar accidents, though this information will not be released publicly.
An Accident Investigation Board will also investigate the matter for a public report on the cause of the accident.
The Reaper crashed 20 miles northeast of Oswego during a routine training mission around 1 p.m. on Tuesday.
According to the 174th Attack Wing, the Reaper took off from Fort Drum and was operating in approved military airspace. It weights eight to ten thousand pounds, has a 66-foot wingspan and costs between $4 million and $5 million.
