Hi Jannick, I'm also a marshal on the mulsanne but at post 31, which is by the tram terminus before the first chicane. We can feel the suction as they come past us at 185+ mph ,an awesome site. I'm with a crowd of Belgian marshals from Zolder and Spa, meeting up with them at Spa for the GP every year. This year will be my 20th in a row !!
