The incident was also mentioned by someone on the UKAR forum. He thought the aircraft was lower than 1000ft (more like 500) whilst in the go around over the Solihull area. The aircraft would have been at 2500ft at this point.

Just shows how difficult it can be to gauge the height of aircraft when they are in a different position than you are used to seeing them.
