the basis for a shared military/civilian air traffic control network and thus share the costs that would otherwise require two complete networks. A series of follow-up studies by NATS all agreed with Zuckerman, pointing out that a military network would need complete information on civilian flights anyway in order to filter out contacts that were scheduled jetliner traffic. There appeared to be no reason not to merge the networks, and the result would be a network once again covering the entire UK. Only minor changes were made to the military network. One was to move the location of the inland radar, originally RAF Bramcote, to a new location further north on the eastern shoreline, RAF Boulmer, which was intended to cover the BMEWS location now that it had also moved to its final position at RAF Fylingdales. This meant the original triangular layout was now an extended line, but this had little effect on the overall performance. The other change was to move the southern-sector control centre from RAF Bawburgh to be beside the new London Area Control Center in West Drayton, which would significantly reduce the cost of the telecommunications equipment. This led to a firestorm of protest within the RAF, because while it was true this would help communications with the civilian network, it made communications with the military radars more difficult, potentially able to be jammed. The argument over this issue raged, but no changes were made in the immediate term. Linesman/Mediator By 1961 any remaining argument was overruled, and on 21 February the Treasury released funding for the newly-christened Linesman/Mediator. Implementation Linesman, whilst part of the "Ahead" plan, evolved out of the study into combining radar information carried out in the late 1950s by the Royal Radar Establishment (RRE) at Malvern with the participation of the Automatic Telephone Manufacturing Company (ATE) of Liverpool. The concept was to reduce the complexity of the existing distributed ROTOR system using multiple Master Radar Stations (MRS) with a single site designated "L1" (Linesman 1). L1 would be able to direct all of the air command using a complete air picture of the UK. During the initial stages of the project RRE became the Royal Signals and Radar Establishment (RSRE) and, in 1962, AT&E was merged with Plessey. Linesman was a comprehensive upgrade of the UK air defence system; along with work on the signalling and communications issues, upgrades to the
