Malaysian authorities released the first report this morning regarding Malaysia Airlines flight 370, which went missing two months ago. According to the investigators' timeline, officials didn't notice for 20 minutes that the Boeing 777 had vanished from the radar and didn't begin its rescue operation for four hours after that.
The report also said the lack of real-time tracking methods resulted in "significant difficulty" in finding the airplane "in a timely manner." The report was first sent to the passengers' families, who were told today to go home and wait for any updates as the airline scales back its briefing schedule. Not a single piece of debris has been located in the two months investigators have been looking for the plane.
CNN, of course, has a full rundown on the report — including information that's missing.
