Every Windsor is a natural born aviator, and there is never any question as to them being selected for pilot training or excelling at it once selected.
That was your actual first option - they would not have been selected for pilot training without passing that selection process on their own merits.
There are very few natural born aviators (and neither prince is), people just work hard during training to achieve the standard.
I'm sure your prejudice won't let you accept that.
Would you be happier that they spent their whole lives as playboys because that would satisfy your green-eyed gaze at those young men whose lives (in your view) are a constant stream of privilege and elitist opportunity?
