PALT Airport System – Ikarus PALT (passenger and luggage together), an experimental design project started in 1982 to allow smoother transfer of passengers from the city to the airplane. It had both customs and check-in/out facilities to handle the process en-route.

A few other prototypes (695.01, 695.02, 692.03) were built, but the project was abandoned in 1986.
