ABSTRACT:
An apparatus comprises a deformable structure surrounding a volume, and means for suspending a fragile cargo in spaced relationship above an impact zone on said deformable membrane. The apparatus is designed to: prevent damage to fragile cargo therein; lengthen a duration of the cargo impact period; reduce terminal vertical freefall velocity of the cargo relative to a terminal vertical freefall velocity of the cargo alone; and lengthen a duration of a cargo/craft fall period for falls from extreme heights. Preferably, the apparatus is spherical in shape, substantially transparent, and has a plurality of flexible strut members for suspending the fragile cargo in spaced relationship above an impact zone of said apparatus.
