1. The method of making a structure for providing egress for persons from an elevated portal, such as the door of an aircraft upon a runway, and safe rapid transport to a lower surface such as that of the earth despite ambient radiant heat energy as great as 2.0 BTU/ft2 -sec., said method including the steps of:

  • providing a flexible air impermeable fabric material which is able to endure said radiant heat energy for substantially 180 seconds while retaining adequate structural integrity and air impermeability;

    forming at least two pieces of said fabric material to predetermined individual shapes for contiguous incorporation into the inflatable portion of a fluid distendable slide structure, said at least two fabric pieces defining a part of said inflatable portion, said slide structure being adapted when inflated to extend outwardly and downwardly at an angle from said portal to said lower surface;

    adhesively securing said at least two fabric pieces sealingly one to the other to define a seam therebetween;

    providing additional outward protection from radiant heat energy only at said seam; and

    utilizing each of the four above-recited steps in forming each seam of said inflatable portion of the slide structure which may in use of said slide structure be exposed to damaging radiant heat energy.
