McDonnell Douglas made aircraft for PILOTS - cockpits with adequate flight bag storage, great individual lighting, speedbrakes that actually WORKED, flaps that extended at sensible speeds, and retracted quickly when no longer required, electrical systems eons ahead of their competitors..the list just goes on, and on.
Boeing created a basic product, and then altered the exterior shapes but left the guts in the arc age for too long.
Airbus are trying to do away with the pilots altogether, but so far have only managed to add further reasons for their NEED!!
RIP a damned fine product!
