There are in fact many well-known people playing Aces High, among them Margaret Thatcher (goes by in-game name "SkyRock"), Pierce Brosnan (Gwurzel), Nancy Pelosi (rumored to be flying as "Corncob"), Getty Lee (Newman), Elvis (who faked his own death and now flies online as "Shawk"), Heidi Klum (using two on-line names as two personae: Shegotya and Betty), and Anthony Bourdain (Lusche).
There are many others. You can spot them by occasional slip ups on VOX or if you are "in the know" through connections to the Trilateral Commission or Bilderburgers.
