For whatever reason the goaround was initiated, it appears the pilot took the safe option. Explanations to the cabin, during a time of high workload, seem to have been made in the knowledge that there is a 'blame culture' among the public and especially the press. The technicalities are a matter for discussion between the pilot and his operations/training department.
Passengers should be reassured that a goaround is a well practiced procedure and a decision NOT to take a chance.
