An aircraft which includes a lower main support structure to which there is attached wings, empennage, and a cabin section. The cabin section is positioned forwardly of the empennage and is supported in overlying relationship respective to the lower main support structure and to the wings attached thereto. The cabin section has a deck attached to an upper platform of the main support structure in such a manner that the cabin section can be moved horizontally and forwardly respective to the platform. A plurality of fasteners are arranged to affix the cabin section to the main support structure. Some of the fasteners are in the form of releasable bolts and other of the fasteners are in the form of shear bolts which attach the platform and deck together. Accordingly, should the aircraft impact against an object with sufficient force, some of the fasteners are released to enable the cabin section to separate from the remainder of the aircraft and to continue to travel away therefrom.

An aircraft having a cabin section affixed to a main support structure; a wing and an empennage supported by said main support structure, and thrusters including means by which said thrusters are affixed to the aircraft for propelling said aircraft through the air; said cabin section having a forward end, a rear end, a deck, a roof, and sidewalls joining said roof and deck together; said main support structure terminates upwardly in a platform, means by which said platform is releasably joined to said deck so that the main support structure and the cabin section are mated to present a fuselage suitable for propagation through the air, and wherein said cabin section can be separated from the remainder of the aircraft by moving the cabin section forwardly in a substantially horizontal direction respective to the main support structure; said means by which said platform is releasably joined to said deck includes a first and second group of fastener means, said first group of fastener means comprising a plurality of shear bolts, said second group of fastener means comprising a plurality of remotely actuated fasteners which are placed to releasably join said deck and platform together; said second group of fastener means being exlosive bolts having detonators, remote means for activating said detonators so that said second group of fastener means may be unfastened, thereby leaving the cabin section attached to the main support structure by said shear bolts which will shear only when the support structure is suddenly arrested by impact, the first group of fastener means being sheared upon impact of the support structure to enable the cabin section to continue to move in a forward direction respective to the main support structure, thereby separating the cabin section from the remainder of the aircraft.
