MOSCOW, October 26 (RIA Novosti) - Six people are feared dead after an Hawker-125 executive jet operated by the S-Air company crashed on Monday while coming in to land in Minsk, a Russian air traffic control source told RIA Novosti.

"The Vnukovo-Minsk flight took off at 21:06 [Moscow time, 18:06 GMT] and disappeared from radar screens at 22:35 [19:35 GMT] on approach to the Belarusian international airport," the Federal Air Navigation Service source said.

According to preliminary information, the plane could make the landing from the first attempt and was lost by traffic controllers following the second attempt to land in normal visibility and satisfactory weather conditions.

The CEO of the S-Air airline, Marat Romashkin, was reportedly on board the plane.

Its fleet comprises several Yak-42D, Tu-134, Yak-40, Hawker-125-700B and Hawker-125-800B planes.
