Abstract: A passenger aircraft with a passenger cabin is described, wherein the passenger aircraft comprises a fully functional door, which is openable and closable and which is adapted for an entrance and an exit of passengers, and en emergency exit door, which is exclusively adapted for an emergency exit of passengers from the passenger cabin. Therein, the emergency exit door is arranged in an area of a fuselage of the passenger aircraft, which is arranged ahead of and/or behind of wings of the passenger aircraft.

Abstract: A fastener device (10) provided with attachment means (20) for attaching an external load (5) and with fastener means (30) provided with a support beam (40) and with anchor means (50) for anchoring said support beam (40). A first mechanical coupling (60) connects said support beam (40) to the anchor means (50) so as to enable the support beam (40) to pivot about a first pivot axis (AX1). In addition, coupling means (70) are hinged to the support beam (40) so as to make pivoting possible about a second pivot axis (AX2), the attachment means (20) being hinged to the coupling means (70) to make pivoting possible about a third pivot axis (AX3). This fastener device (10) includes automatic folding means (100).

Abstract: A nuclear power plant (18) and its heat exhanger (26) are enclosed in an envelope (22) which is suspended above a bored shaft (14) from a support stem (30). When appropriate, the stem (30) can be melted by a furnace (34) to drop the envelope (22) to the bottom of the shaft (14). Sand (42) can then be dropped onto the envelope (22) through a drainage pipe (46). While the nuclear power plant (18) is operating and suspended in the shaft, spent fuel rods (70) are dropped into a sand blasting machine's hopper (130), mixed with sand and dropped into a bag (134) containing a small explosive device. The bag (134) is then dropped to the bottom of the shaft (14) and the explosive detonated to scatter the contents of the bag (134). Optionally, more sand or earth is then added to reduce heat and radiation to acceptable levels.
