MOSCOW, May 11 - RAPSI. Investigators will question the Sukhoi Civil Aircraft workers involved in developing the Sukhoi Superjet-100 that crashed yesterday in Indonesia, Investigative Committee spokesman Vladimir Markin said.

The SuperJet-100 crashed on May 9 during a promo flight. The aircraft carried passengers from five countries, including eight Russians when it crashed on Mount Salak at a height of 5,200 feet.

"I would like to stress that law enforcement agencies will investigate the case not only at the scene of the crash in Indonesia, but also in Russia where they will question the technical staff involved in preparing the aircraft for the flight, as well as the Sukhoi Civil Aircraft representatives responsible for developing and commissioning aircraft," Markin said.
