...first, investigators believed the disaster might have been caused by massive structural failure. Though Boeing 747s are among the sturdiest passenger planes in the world, a Japan Air Lines 747 crashed on a domestic flight in 1985 after a rear bulkhead ruptured as the result of a faulty repair job, killing 520 of the 524 aboard. But one important difference between the Japan Air Lines crash and the Pan Am tragedy was that the pilot of the Japanese plane was able to talk to ground control for half an hour as he tried unsuccessfully to land his mortally wounded craft...
...seal on a booster was responsible for the Challenger disaster. In addition, Discovery has a pressure-vent-line leak in one of its orbital maneuvering system engine pods, which came to light several weeks ago. NASA says repairs to the OMS pod, which involve cutting through a bulkhead, could delay the launch anywhere from a week to two months. NASA insists that the repairs and continuing caution during the countdown will be sufficient to fly the orbiter with confidence. Perhaps, but Discovery's trip into space may be farther off than anyone expected...
...when a replacement engine that had been improperly mounted on the wing of an American Airlines DC-10 broke free on takeoff from Chicago's O'Hare International Airport, causing a crash that killed 275. Only three years ago, the worst single-plane accident in history occurred when a bulkhead ruptured on a Japan Air Lines 747, destroying the tail assembly and sending the jumbo jet crashing into a mountain near Tokyo, killing 520. Boeing later admitted that its technicians had incorrectly riveted the bulkhead during a repair job seven years earlier...

...gear, it has much more living space inside. Crew members have separate "cabins," or cubicles, each equipped with a folding chair, a desk, a mirror and a sleeping bag. The common area of the space station's living unit features a dining table, a buffet built into a nearby bulkhead, and exercise equipment for the crew. The station is fitted with a large number of portholes, providing views from all four sides of Mir. One oversize porthole has been installed in the floor for viewing the earth's surface...
