Within in the Army, even in this modern age, there are still elements that simply hate the idea of a soldier with any kind of wings on their uniform, we were regarded as 'elitist' and a bad influence, needed to be kept in our place, that sort of thing. In our small helicopter unit my boss was one of Stirling's originals from North Africa who went right through the war at the very sharp end and his opinion was these types, who thought we were 'elitist', had probably done rather badly at staff college!
The sole purpose of the RAF is to fly aeroplanes and the sole reason for an aircraft carrier is to enable aeroplanes to fly, but to this weird bunch I mention above, the idea of a soldier with wings was simply 'not on'.
