Getting a mental picture as much as anything, but also not realising that the poster was outside the UK.
In the UK, for most people, MEng is the elite product, and an MSc is mostly taken by people who weren't good enough to either stay on an MEng course, or get a job. Of course, that's generalising, as high quality specialist MSc courses do exist - Cranfield being the premium provider in the UK.
Also of course anybody going to Masters level is showing a commitment to their engineering education beyond the minimum, and whilst I don't like the term "backup", it is more valuable than a vanilla BEng.
There is also something not often explored, which is that the aviation world is relatively homogenous, so somebody with an aerospace engineering degree who then goes into flying training, will by many employers be regarded as simply continuing their professional aerospace education, and respected for that. For example, the CPL/ATPL groundschool syllabus contains a lot of aircraft systems knowledge not in degree syllabi, and the flying knowledge is essential in some professional engineering jobs (particularly those related to flight test).
