The a/c in question made an approach to EGSS and excecuted a go around due to the severe turbulence. There was a severe squall to the west of EGSS meaning the a/c had to turn left on the go around. Most of the a/c behind him went around as well. The pilot requsted the weather for Luton and East Midlands which were worse so he elected to go to EGGP. With the severe headwinds en route to EGGP his ground speed bearly exceeded 230kts.
