I just hate it when I have to take a bus to my airplane somewhere out on the airfield and then get out and walk up stairs to get on board. Hannes Seeberg has designed the SkyLift - a bus that takes you to the plane and "lifts" you aboard. This is a far better way to enter the smaller aircrafts and those parked out of reach for the traditional boarding bridges.
According to Seeberg the SkyLift is "Designed for safety, speed and capacity, two elevators and a bridge provide best possible conditions of comfort for passengers. It helps solve problems that occur within passenger staircase - such as falls, bottleneck-effect, security risks and accessibility."
