i think what we're missing out of the equation here is over what kind of time frame did they go from a cruising altitude of 35,000 feet down to an extremely low altitude for an aircraft like this of we were just calculating how long, mitchell, it would take if you did it at a reasonable descent rate. >> reasonable descent, 15-20 minutes. >> reporter: what we've done so we set the scenario here we are flying over the strait of ma lack ca, just as the aircraft has done in a northerly direction and right now at 6,000 feet pause we figured you didn't want us to talk for 15, 20 minutes if we took you all the way down. over the south part you have the northern part of malaysia and in the distance ask, the island of sumatra. the jumbo jet flying at 4,000
