In February 1944 Harris called a meeting at High Wycombe to discuss the destruction of the V3 site. The meeting included the AOC of Bomber Command Arthur Harris, the AOC of the Pathfinder Force, Air Vice Marshall Bennett and 5 Group AOC Cochrane, who brought along with him Cheshire. It was chaired by deputy air officer commanding-in-chief Robert Saundby. Bennett was informed of the accuracy needed to mark the target. He dismissed the idea, stating that it could not be done. Cheshire offered that it could be achieved if attempted with a low-level marker aircraft. Bennett rejected this as well, stating that a low-level flight against a well-defended target would not be survivable. The problem was withdrawn from the Pathfinders, but was given to 5 Group to see if they could work out a solution. They were pleased to have the opportunity, as it was what they were hoping for. There would be a delay in the operation, as the large bomb that Barnes Wallis proposed to destroy the target at Mimoyecques was still under development. This allowed Cheshire and Martin time to develop a technique by which they could accurately mark and hit within yards of the target.
