Cessna-Gulfstream Speed Duel Could Hit Mach 0.95 Limit

The transonic speed spat between Cessna’s Citation Ten and Gulfstream’s G650 is likely to hit the stops at Mach 0.95 when it encounters not “the sound barrier” but required safety margins. With the Ten’s top speed now pegged at Mach 0.935, Gulfstream’s G650 could thus leapfrog the Ten only slightly, if the Savannah-based aircraft manufacturer even chooses to do so.
