 The issue of minimum range continued to be raised , working its way through the Air Ministry and eventually to Harold Lardner , head of what was then known as the Stanmore Research Centre . Rowe and his deputy Bennett Lewis were called to meet with Lardner to discuss the issue . Apparently without informing Lardner of Bowen and Hanbury Brown 's potential solution , or the fact that they could not work on it due to the ongoing installations , they agreed to have Lewis investigate the matter . Lewis then sent a contract to EMI to see what they could do . According to both Bowen and Hanbury Brown , Rowe and Lewis instigated these events deliberately to pull control of the AI project from the AI team .
