Coming into LHR over London just turning towards final approach our BA 767 lurched and shuddered seevrely but immediately recovered. A moment later the BA captain speaking voice says -'Sorry about that-if you have ever heard the term wake turbulence thats what it feels like'
Like hitting a substantial speedbump rather too fast -very noticeable but not very scary in a 76'. But I understand how it could be a real danger to a small bizjet or simialr mixing it with the widebodies which certainly happens at some airports , but then thats what separation is for right?
