In that same bunker, 10 feet below the bustling streets of Whitehall, a pudgy, biro-chewing, poodle of a man sits lost in thought as the Battle of Britain rages on a huge plasma screen in front of him. 505 Games couldn't have picked a more appropriate location for demonstrating its imminent (4th September) combat flight sim.
