Jacko:
Why did UAS undergraduates have to do the EFTS course during their time at Uni?
See above:
The “system” (outside the RAF) was going to force the closure of UASs. In order to defend the existence of the UASs, they were tasked to do Elementary Flying Training, and thus the argument could be used that they were an integral and essential part of flying training within the RAF, and they were therefore saved from extinction.
