Randolph Bonnist, pilot in Martha's Vineyard plane crash, died Thursday

The pilot of a private plane that crash-landed at Martha's Vineyard Airport on July 15 has died, according to a statement from Cape and Island District Attorney Robert J. Galabois.

Randolph Bonnist, 79, of Norwalk, Connecticut died Thursday night at Boston Medical Center in Boston, Galabois' statement said.

According to police, the plane, a 2006 Piper Meridian, flew out of Westchester, New York, on July 15. While landing on Martha's Vineyard, around 3:15 p.m., the pilot appeared to have "suffered a medical emergency," according to police. Bonnist's wife, Robin, the passenger on the plane, took over the controls in order to land.

The resulting hard landing, in a grassy area near the runway, caused the plane's wing to break in half, police said.

Randolph Bonnist was flown to Boston Medical Center in "serious life-threatening condition," according to police. His wife was evaluated at Martha's Vineyard Hospital and released.

Representatives of the Federal Aviation Administration and the National Transportation Safety Board are investigating the cause of the crash. No foul play is suspected, according to Galabois' statement.
