This state of affairs was considered distasteful and there was some consideration given to methods to allow bombing during the day. Two ideas became popular. The "schnellbomber" was a very fast aircraft that would simply fly right past the slower fighters due to the extra power of their twin-engine designs. This was demonstrated with great effect in air races, where light twins easily outperformed fighters. But this situation only existed for a short period until more powerful aircraft engines emerged in the mid-1930s and once again a single-engine fighter could catch a twin-engine bomber. The other idea was the escort fighter that would attempt to break up attacks by the defense before they could reach the bombers. To have the desired range, the aircraft had to carry a large fuel load, and at the time this demanded a twin-engine aircraft. Such a design would not be able to maneuver with the single-engine day fighters, so attention was given to outright performance.
