Well they may have been The Queen of the skies
I flew the 747 after flying the VC10. When doing the 747 ground school course, I was mildly surprised that many of the 747 systems were remarkably similar to the VC10s. For example, the electric system was almost identical apart from which busbars were synchronised. Late, I found out that many of the design engineers who had worked on the VC10 had been employed by Boeing when work on the 10 finished, and they worked on Boeing's new project - the 747. So, rather than referring to the 747 as "The Queen of the Skies", it would be more accurate to refer to it as "The Princess". The daughter of the rightful Queen - the VC10!
Anyone who has flown both will probably agree with me.
