My dad was a pilot for United, and flew the 747 from its introduction (1970?) until he retired in 1973. I rode on them several times in the 70's, and don't remember an aft lounge. I did spend most of my time upstairs, however. It was configured with a semi-circular sofa in the rear part of the lounge, with a low table in the middle, and had several 2 and 4-chair seating groups, all with rotating seats. The seats themselves were covered in a textured heavy vinyl/plastic upholstry, that held up well against spillage from the drinks people carried around. There were only three windows per side in the early 74's, so the view outside wasn't that great. You could see the wingtip and outboard engine however, which was fascinating for a 10-year-old plane nut. There was a small bar/service-area forward, and to the left of the spiral staircase, which usually had a F/A stationed there, to serve the people in the lounge.
The initial 747's were mostly flown to Hawaii. My dad was based at LAX
, and that is what he flew for those last years before retirement. I'm pretty sure they flew out of SFO
too, and probably from both of those cities to JFK
, although I'm not positive
One smooth landing is skill. Two in a row is luck. Three in a row and someone is lying.
