It’s been nearly one year since 298 people were killed after a commercial passenger plane broke up over the Ukraine.

U.S. officials concluded Malaysia Airlines flight MH17 was struck by a missile and shot out of the sky. A final report from investigators has yet to be released but CNN has learned new details from the draft investigative report for the July 17, 2014 incident.

Dutch accident investigators say that evidence points to pro-Russian rebels as being responsible for shooting down MH-17, according to a source who has seen the report.

The Malaysian Airlines flight went down in the Donetsk area of Ukraine. According to two sources with knowledge of the investigation, a draft of an investigative report authored by the Dutch Safety Board, the lead agency in the investigation, has been distributed for review to numerous agencies around the world including the National Transportation Safety Board, Federal Aviation Administration and Boeing.

The draft investigative report is several hundred pages long. According to one source close to the investigation the draft report included the exact type of missile used to bring down MH17 and the trajectory of the missile.

Another source with knowledge of the report’s details says it gives a minute by minute timeline of flight MH17. This source also says not only does the draft report pinpoint where the missile was fired from it identifies who was in control of the territory and pins the downing of MH17 on the pro-Russian rebels.

According to both sources, the report also pins some blame on Malaysia Airlines for how its planes were dispatched that day.

Some airlines were avoiding the conflict zone. According to the report Malaysia Airlines was not reading other countries’ notice to airmen or NOTAMs and it continued to fly over the zone. Notice to airmen or NOTAMs are written notifications issued to pilots before a flight, advising them of circumstances relating to the state of flying, and those notifications can include warnings of potential dangers like conflict zones.

U.S. Airline Carriers for example make decisions about where to fly and where not to fly based on notice to airmen (NOTAMs) that different countries issue to their pilots. If for example, based on intelligence, Britain warned its pilots to avoid flying over a certain country U.S. Carriers would read and consider those warnings and decide if they too will avoid the area.

The Dutch Safety Board is investigating the crash of flight MH17 but it is also investigating the decision-making process pertaining to safety when determining flight routes.
