Today’s invention is a new way to get people boarding an aircraft.
The essential difference is that the unit of boarding would be the seat row.
Rows of seats would be placed on a bus or buses (in reverse order to the onboard seating plan).
When the buses arrive at the plane, the disembarking rows all slide forward and are withdrawn automatically from a side exit, at exactly the same rate that rows are embarked from the rear (or vice versa).
This allows people to take as long as they like getting seated on the bus, so that the boarding process itself can be very rapid.
