ST. IGNACE, Mich. - The Coast Guard has found the wreckage of a single-engine plane on the shore of Lake Huron. The two men aboard, including an Amazon.com executive, were deceased.

Search and rescue controllers at Coast Guard Sector Sault Ste. Marie, Mich., were contacted by a Michigan State Police 911 dispatcher at 10:07 p.m. Saturday, after the dispatcher was called by a concerned family member reporting the men overdue, the Coast Guard says.

The reporting source said the men departed St. Ignace en route to Mackinaw Island in a Piper Saratoga and were expected to arrive at about 8 p.m. The flight is only about 4.5 miles and should have taken only about six minutes.

On board were Tom Phillips and Joe Pann. Phillips was in his late 50s, and Pann was in his late 20s. Both are from northern Michigan.

Shortly before noon Sunday, a Coast Guard aircrew involved in the search effort received a signal from a 121.5 MHz emergency locator transmitter. When they investigated the transmitted signal, they found the plane wreckage about 100 yards from the shore and about three miles north of St. Ignace, Mich.
The cause of the crash is not known.
