Task: Question Generation
Input (English): Although night air defence was causing greater concern before the war, it was not at the forefront of RAF planning. Most of the resources went into planning for daylight fighter defences. The difficulty RAF bombers had navigating in darkness, led the British to believe German bombers would suffer the same problems and would be unable to reach and identify their targets. There was also a mentality in all air forces that, if they could carry out effective operations by day, night missions and their disadvantages could be avoided.
Output (English): What did the RAF put most of their resources into?
