Text, (NASA says that the rotating forces in an aircraft wake vortex can reach 300'/sec., a virtual <horizontal tornado!)
Your quote, "I don't doubt what NASA has said but is this in the immediate vicinity of the airplane or is it still this strong after 90 seconds."
I experienced severe wake turbulence 45 miles, (5 minutes time wise), in trail of another B707. (distance reported by ATC) This happened in a completely stable air mass. The ride was smooth as glass, until the point I penetrated his wake, 500' below our assigned cruising altitude of 37,000'.
