So someone lands long & is slow to vacate, hardly fair to condemn the entire workforce of Qatar. Having had to Go-around twice at LHR recently (on separate occasions), both due to aircraft being slow to exit the runway, I cannot see what your point is. Go arounds are a fact of life, poor airmanship would be landing with one still on! Oh & the airlines that were slow to vacate were BA & BMI, while you are at it why don't you condemn all of their work forces as well!
