I know that there was no danger to the aircraft but surely if the aircraft had passed the point at which the gear was normally lowered and was then unable to land because of this, an error must have been made by the crew, hence my reason for thinking that a report should have been raised to highlight the error.
You presume that the aircraft went around because the crew forgot to lower the gear.
It is called a 'go around' for a very apt reason, that it involves going around, normally maintaining runway heading before a circuit to land, so the fact that the crew continued in the direction of the landing runway would be normal procedure, they can hardly break off the approach and do a 180 when it is likely that other aircraft are on the approach also.
