Divers resumed their search of Lake Michigan on Wednesday for the twin engine medical transport plane that crashed on Monday afternoon.
Coast Guard officials say their goal is to recover as many of the human remains of those on board that they can.
Officials say the plane was carrying a transplant organ team of four people when it reported engine trouble and crashed shortly after take-off.
On Tuesday, rescuers found some human remains during their search and police say some debris had also washed up on shore.
The NTSB is on-site and still investigating the cause of the crash.
