American Airlines is operating Airbus A300-300's and its direct competitor, Boeing 777-300's, side by side. Why Airbus? Because AA bought US Airways and acquired their A330's. Details of the two planes are interesting: -- The 777's cockpit windows are blended smoothly into the nose which tapers to a point like spritzer bullet. By contrast, the. A330 has more of a stepped windshield like a car (anyone know why?) Also, the A330's passenger windows and floor angle up slightly at the back. At the back of the cabin you're walking slightly uphill (again, anyone know why?) Both planes look impossibly long like a pencil with wings. A feat of engineering. Forgive me for rambling but I love planes!
