Ogonowski was a pilot in the U. S. Air Force during the Vietnam War, assigned to Charleston Air Force Base, South Carolina, ferrying equipment to Asia and sometimes transporting the bodies of fallen American soldiers in C-141 transport aircraft. Following his service commitment, he resigned his commission under honorable conditions and separated from the military with the rank of captain.[1][4]
Ogonowski became a commercial pilot in 1978. For 23 years, he flew airplanes for American Airlines, and was a member of the Allied Pilot Association.[1][5] Ogonowski had joined the airline as a flight engineer after previously serving that role in the Air Force.[6]
During the course of his commercial piloting career, he met Margaret, a flight attendant[1][5] who went by the nickname "Peggy",[7] whom he later married.[1][5]
Ogonowski was also an avid farmer, who secured 150 acres of farmland on Marsh Hill Road in Dracut through the federal Agriculture Preservation Restriction program. He raised hay, corn, pumpkins, blueberries, and peaches.[1] He was a leading advocate for farming in Massachusetts, particularly in aiding immigrant farmers from Cambodia.[2]
Ogonowski was survived by his wife Margaret and daughters Laura, Caroline, and Mary Catherine.[5] His younger brother, Jim Ogonowski, who is also an agricultural activist, made an unsuccessful run for the United States House of Representatives in 2007.[9]
In 2002, Ogonowski and Flight 11 flight attendants Betty Ong and Madeline Amy Sweeney were the inaugural recipients of the Madeline Amy Sweeney Award for Civilian Bravery,[10][11] an honor that the Government of Massachusetts instituted to award annually at least one Massachusetts resident for displaying extraordinary courage in defending or saving the lives of others.[12]
A remote controlled model aircraft flying field in nearby Tewksbury, Massachusetts, was dedicated to Ogonowski.[13]
The University of Massachusetts Lowell, presented Ogonowski with a posthumous honorary doctorate at its 2003 commencement ceremony at Tsongas Arena.[3]
The USAID Farmer to Farmer program was renamed the "John Ogonowski and Doug Bereuter FTF Program" as part of the 2008 Farm Bill.[14]
At the National 9/11 Memorial, Ogonowski is memorialized at the North Pool, on Panel N-74, adjacent to the name of Kathleen A. Nicosia, a friend and flight attendant also killed on board American Airlines Flight 11 that day.[15]
