One hour and 34 minutes passed between the time Malaysia Airlines Flight 370 took off from Kuala Lumpur International Airport and when it was last observed on radar, hundreds of miles off course.
The fate of the aircraft is still unknown, but the gaps in that 94-minute flight period are getting filled in as more information is obtained by analysts and shared by authorities.
The latest update comes from Thailand, where a Royal Thai Air Force spokesman told CNN that Flight 370 disappeared from its radar heading east at 1:22 a.m. and then an unknown aircraft -- possibly Flight 370 -- appeared six minutes later, flying in the opposite direction. That information is included in the timeline below, which was compiled by CNN's Richard Quest, Kevin Wang and Ram Ramgopal.
All times local on Saturday March 8, 2014 (March 7, 11:41 a.m. ET -- switch to Eastern Daylight Savings Time had not happened):
