Nevertheless, in 1963, von Braun, reflecting on the history of rocketry, said of Goddard: "His rockets ... may have been rather crude by present-day standards, but they blazed the trail and incorporated many features used in our most modern rockets and space vehicles".[71] He once recalled that "Goddard's experiments in liquid fuel saved us years of work, and enabled us to perfect the V-2 years before it would have been possible."[72] After World War II von Braun reviewed Goddard's patents and believed they contained enough technical information to build a large missile.
Three features developed by Goddard appeared in the V-2: (1) turbopumps were used to inject fuel into the combustion chamber; (2) gyroscopically controlled vanes in the nozzle stabilized the rocket until external vanes in the air could do so; and (3) excess alcohol was fed in around the combustion chamber walls, so that a blanket of evaporating gas protected the engine walls from the combustion heat.
