When the war broke out in 1914 scientists already knew how to remotely control a vehicle with radio signals. In 1905 Spanish Engineer Leonardo Torres-Quevedo demonstrated a radio controlled boat that accepted commands from more than a mile away. During the war Germany produced and successfully used the Fernlenkboot, an unmanned, wire guided speed boat that carried a 700kg warhead. In addition scientists had long understood how to use gyroscopes to keep a craft steady. The Howell Torpedo designed in 1870 used gyroscopic force to keep it steady and on target. It should also be noted that from the very beginning there was significant research on unmanned flight, The Development of Unmanned Aerial Vehicles in Germany (1914 – 1918).
Although in 1914 there was a great interest in unmanned flight and an understanding of remote control and gyroscopics did scientists have a deep enough knowledge of aerodynamics to produce a primitive, wire-guided gravity bomb?
These were amazing weapons. However were there scientific or engineering limitations that stopped designers from building primitive versions of these weapons during WW1?
