PETALING JAYA, Malaysia - There was nothing out of the ordinary happening in the cockpit of MH17 in the minutes before the plane broke up in mid-air while flying over eastern Ukraine on July 17.
The preliminary report on the crash said the cockpit voice recorders (CVR) of the B-777 did not register any aural alert or warning of aircraft system malfunction.
"There was also no indication of any emergency or abnormality, judging from the communications between the flight crew members until the end of the recording," the report said.
"The replay of the CVR matched Air Traffic Control (ATC) communications with the aircraft. The recording also included crew communications, which gave no indication that there was anything abnormal during the flight.
"The recording then ended abruptly," it said.
Information from the plane's Flight Data Recorders (FDR) showed that the engines were running at normal cruising power and were operating normally.
It added that the team of experts investigating the crash was able to retrieve all the data despite external damage to the black boxes containing the CVR and FDR.
