What's it called and where to get one
At some point I think we've all seen those big bus like things that could raise or lower themselves to the door height of the plane and which would be used to shuttle passengers from the airplane stand to the terminal building.
I know they've been used at many airports around the world, even today and I'm considering the purchase of one or more but not have much luck sourcing any for sale or a supplier.
Can anybody tell me
1) What are they called
2) Where can I get one
Thx in advance
