Don't know if this is of interest to anyone, was traveling on LH918 from FRA to LHR this evening (PAX). As we were about to touch down at LHR the PIC performed a very nice go-around. When he leveled out above London, he explained that a Scandinavian had not made it off the runway in time and we thus avoided collision.
2nd landing attempt went well. Pilot performer really well IMHO - as I would expect from LH. Crew was well composed, too.
I wonder if this happens frequently at LHR due to the airport working beyond capacity?
