> Seems to me like an airplane on the ground is a lot safer to stand in than a fully packed bus in a busy city. Any ideas? A plane is designed to fly sitting passengers, a city bus is designed to drive standing passengers. A driving plane has very poor suspension - it's bumpy and the bumps are leveraged by the tall landing gears. Inside the plane, people won't just be standing, they will be unpacking the overhead lockers, handing around heavy luggage over people's heads. Busses don't have overhead storage for heavy items, probably for this exact reason.
