British intelligence soon discovered the nature of the Kammhuber Line and started studying ways to defeat it. RAF Bomber Command sent aircraft one at a time to force the defenses to be spread as far apart as possible, meaning that any one aircraft would have to deal with little concentrated flak. The "Himmelbett" centers were only dealing with perhaps one or two planes at a time, making their job much easier. At the urging of R. V. Jones, Bomber Command planned attacks against a target at a time, sending all of the bombers in a "bomber stream", carefully positioned to fly down the middle of a cell. The Himmelbett centers were faced with hundreds of bombers, countering with only a few aircraft of their own. So successful was this tactic that the success rate of the night fighters dropped almost to zero.
