WICHITA, Kan. (AP) — The Regional Forensic Science Center has positively identified three of the four people killed when a small plane crashed into a flight safety training facility last week at Wichita Mid-Continent Airport.

KWCH-TV reports the victims are 48-year-old Nataliya Menestrina, 78-year-old Jay Ferguson, and the pilot of the plane, 53-year-old Mark Goldstein. The identity of the fourth victim had not been confirmed as of Tuesday.

The twin-engine Beechcraft King Air drifted left of the runway after taking off Thursday, then made a steep left bank before plunging into the Flight Safety International Learning Center at the airport.

Goldstein and three people inside flight simulators in the building were killed. Five others were injured.
