The 47 was boss. It’s big and maintenance requirements are huge but the money those work horses have made is also huge. The quest to burn less fuel bows to payload and payoff.Honestly if I could just walk out the door with them I would. And pass them out for free. There are so many metal tools just getting pushed into the corner.
The 747 was the last plane completely built in house. So a lot of the work done on them isn't done anymore.
