1. In a method of transporting a freight by plane between a departure air terminal and an arrival air terminal, some flight distance therefrom, the improvement comprising the steps of: at the departure air terminal: depositing a mechanically resisting transfer sheet sufficiently large for an edge portion to project from at least two opposite sides of the freight load on a special air type pallet, placing said freight on said sheet and carrying said air pallet carrying said sheet and said freight into the plane; and at the arrival air terminal: removing the air pallet carrying the sheet and the freight, from said plane, grasping the projecting edge portions of the transfer sheet and tensioning the shEet to support the freight so as to enable the air pallet to be removed, removing the air pallet and placing the same into the plane, replacing the air pallet with a conventional type pallet, removing the tension from the sheet so as to place the freight on said conventional type pallet, and releasing the sheet edge portions.

4. In a method of transporting a freight by plane between a departure air terminal and an arrival air terminal, some flight distance therefrom, the improvement comprising the steps of: at the departure air terminal; depositing a mechanically resisting transfer sheet sufficiently large for an edge portion to project from at least two opposite sides of the freight load on a special air type pallet, placing said freight on said sheet and carrying said air pallet into the plane, and at the arrival air terminal: removing the air pallet carrying the transfer sheet and the freight by a conveyor moving in a first direction towards a transfer station, moving a conventional type pallet towards said transfer station on a second conveyor whose path intersects that of the first conveyor at said transfer station, grasping the projecting edge portions of the transfer sheet and tensioning the sheet at said transfer station so as to enable the air pallet to be removed from beneath said freight load, removing said air pallet from said transfer station and from beneath said tensioned sheet in the same direction as the direction of movement of said conventional type pallet and to the side opposite that from said conventional type pallet, replacing said removed air pallet with a conventional type pallet beneath said tensioned sheet, removing the tension from said sheet so as to place the freight load on said conventional type pallet, and releasing the sheet edge portion, and conveying the conventional type pallet and said transfer sheet and said freight on a conveyor in line with and moving in the same direction as the conveyor in line with and moving in the same direction as the conveyor initially moving said air pallet at the arrival air terminal to said transfer station.
