After becoming too low during a Ground Controlled Approach (GCA) to runway 26 at Northolt the Super Constellation aircraft was directed to climb and turn left to avoid high ground. In the course of the turn, the aircraft passed close to an Olympic Airways Boeing 727 which was making an Instrument Landing System (ILS) approach to Runway 23L at London Heathrow. There were no casualties or damage and both aircraft subsequently landed safely.
Probable Cause:
The incident was caused by the actions of GCA controller as a direct result of the failure of the commander of the Super Constellation to follow the talk-down instructions and to maintain his assigned height.
