FROM THE MOSCOW TIMES.
The plane made its first approach toward Adler airport around 3 a.m. local time but was unable to land due to poor visibility. The plane circled and made a second approach, during which visibility again dropped below minimum acceptable levels. Air traffic controllers advised the pilot to climb to 600 meters.
It was during the climb, at 3:15 a.m., that the plane made a sharp turn and dropped off Adler airport's radar, a member of the airport's technical staff said, Interfax reported.
"The A320's speed was about 250 kilometers per hour, which may not have been enough for it to gain altitude," the source said.
The plane hit the water at a steep angle, Beltsov said.
Is there much chance the aircraft stalled?
