What: Lee H Aviation Inc. Cessna 421C en route from Slidell, La., to Sarasota, Fla.
Where: Gulf of Mexico
When: April 19 2012
Who: pilot
Why: The plane took off normally from Slidell at 6:43 a.m., but en route lost contact with ATC and began flying in circles over the Gulf of Mexico.
Around 8:45 a.m, two F-15s that flew in to check on the plane found it flying between 25,000 and 35,000 feet with the windshield iced over. The pilot remained unresponsive. The plane landed “softly” intact and right side up in the water around 12:10 p.m., approximately 120 miles west of Tampa. The pilot was unconscious or incapacitated.
The 87-foot cutter Coho was scheduled to respond as well as a HC-144 plane from Mobile, Alabama and a MH-60 helicopter in Clearwater.
The pilot may have lost consciousness due to hypoxia, or a lack of oxygen.
