Multi-story retrofitting building escape units. In aspects, the units are prefabricated and may be stacked. In embodiments, water or other fire-deterrent liquid or foam may be stored or delivered in tubular legs of the unit or tubes with in the legs. A hose or other mechanism to apply the water or other liquid is located in one more units. Each unit comprises stairs that link up with stairs on units above or below so occupants can climb down, for example, and emergency personnel can climb up, for example. In aspects, one or more walls of the unit are fire walls or otherwise fire-retardant, fire-proof, or fire-resistant.

An emergency escape slide container includes a first portion having a first end wall and a first side wall, the first side wall and the first end wall defining a first storage space that is sized and shaped to receive an emergency escape slide. The first side wall also includes a first rolling mechanism. The emergency escape slide container also includes a second portion having a second end wall and a second side wall, the second side wall and the second end wall defining a second storage space sized and shaped to receive the emergency escape slide. The second side wall also includes a second rolling mechanism. The first portion and the second portion cooperate to define a third storage space therebetween, the third storage space being equal to a combination of the first storage space and the second storage space.

An inflatable tube for an inflatable slide may comprise an interior surface extending from a first longitudinal end of the inflatable tube to a second longitudinal end of the inflatable tube opposite the first longitudinal end. An exterior surface is opposite the interior surface and may include a land portion located proximate the first longitudinal end. A channel portion may extend from the second longitudinal end. The channel portion may include an attachment portion located proximate a distal longitudinal end of the channel portion. The interior surface of the attachment portion may be configured to attach to the land portion of the exterior surface.

A mobile aircraft simulation tool that includes a simulated aircraft body extending between a front end and rear end along a central axis X and having a length of between 10 and 60 feet. The simulated aircraft body includes a plurality of windows, one or more doors, an internal cavity, and a passenger cabin within the internal cavity having a plurality of seats.

A support arrangement for an inflatable evacuation system may comprise an inflatable member configured to be elongated and stiffened in a longitudinal direction in response to being in an inflated condition, a protrusion extending orthogonal to a surface of the inflatable member, a tensile member attached at at least two locations to the inflatable member on opposing sides of the protrusion and being slidably engagable over the protrusion so as to maintain about equal tension in the tensile member on opposing sides of the protrusion, and a sleeve attached to the protrusion configured to maintain the tensile member laterally relative to the protrusion even as the tensile member is able to slide longitudinally.
