A private plane that crashed in upstate New York over the weekend was carrying a close-knit family of physicians and distinguished recent student-athletes, bound for a trip to the Catskills for a birthday celebration and the Passover holiday.

Karenna Groff, a former MIT soccer player once named the NCAA woman of the year, was one of six people killed in a plane crash.

The twin-engine aircraft, a Mitsubishi MU-2B, went down shortly after noon Saturday in a muddy field in Copake, New York, near the Massachusetts line, killing all six people aboard, according to authorities.
