Incident at NAT TRACK W


2010-10-29: At 02:10Z, DAL74, Boeing 767-300, enroute from Atlanta (KATL) to Milan (LIMC), was by 50N040W at 02:01Z at 34,000 ft., estimating 51N030W at 02:42Z when it requested clearance to descent to 32,000 ft. due to moderate to severe turbulence reported by aircraft between 30W and 25W.
