I like the sense of continuity with Heathrow’s history.
Love it or hate it, and I can do both depending on the terminal I happen to be in, LHR has a significant place in the history of world commercial aviation since it was just a row of tents in the late 1940s. And in her own way the Queen has been part of that history. In the 1950s, the Queens’s departure from and return to London Airport was headline news, stepping on or off an Argonaut, Stratocruiser, or Hermes (;-), and on one solemn famous occasion returning as monarch.
I don’t mind seeing her name above the door!
