LAX & SLC EGPWS Sim scenarios are dereguer in our schoolhouse. There's nothing subtle about a terrain escape maneuver! 250KIAS is the maximum below !0,000 in the Continental US. There is no avenue for a controller to approve faster. Some pretty funky winds this week, so its possible they had a 100kt tailwind at 6000... but if they were faster thats another visit to the Chiefs office...
