I went into a British Airways 747 cockpit in the ‘90s. We were over the Atlantic. That really wasn’t unusual pre 9/11. The pilots let a bunch of people up on the flight deck during that flight.
Me too. I was flying biz class on a Singapore Airlines flight from Tokyo to LA in the late 90’s, and a rock star was in the cockpit for both takeoff and landing. The upper cabin on the 747 was visibly concerned when the guy, complete with dreadlocks, was escorted up from first class.
