None of the astronauts slept very long before awakening to the most momentous day of their lives. Collins got six hours, Aldrin and Armstrong five apiece. During Apollo's eleventh revolution of the moon, Aldrin and Armstrong donned their space suits and crawled through a tunnel for a final checkout of the lunar module before its long separation from the command module. They paid particular attention to Eagle's propulsion systems?the tanks containing the hypergolic fuels that fire the descent and ascent engines, and the pressure gauges on the helium that forces the fuels into the combustion chambers, where...
...first hint of more serious trouble occurred after Apollo 10 had slipped into its nearly circular 69-mile orbit around the moon. Crawling through the tunnel connecting Charlie Brown to Snoopy, Stafford discovered that the padding on Charlie Brown's hatch had been ripped during the pressurization of the lunar module early in the flight, allowing snowlike fiber-glass insulation to escape and drift around the tunnel interior. During Apollo's eleventh revolution, as Stafford and Cernan prepared to undock Snoopy for its descent toward the moon, the astronauts found that they could not depressurize the connecting tunnel...
Angle of Twist. To solve this problem, Stafford and Cernan reopened Snoopy's sealed hatch. Much of the oxygen in the tunnel promptly flowed into the lunar module, where the pressure was less. The excess oxygen was then released into space through a vent in Snoopy...
...helibus and Hovercraft. Architect Stanley Tigerman estimates it would cost a relatively modest $500 million. Closer to approval, however, is a $1 billion dike-protected jetport 35 ft. to 55 ft. below the water level of Lake Michigan and connected to the Loop by six miles of causeway, tunnel and bridge. Says Chicago's Aviation Commissioner William Downes Jr.: "The main objection comes from the save-our-lakefront fraternity who don't realize that an airport six miles out wouldn't be visible from the shore except as a large shadow from high buildings...
...Sealed Tunnel. After probing for three months, the diggers struck a rectangular masonry shaft that began at the city level of Ahab's time (about 850 B.C.) and dropped past the debris of 13 older cities. As Yadin was removing rubble near the bottom of the shaft, "a rush of hot air hit me in the face." He had uncovered a 12-ft.-high tunnel that had been sealed since Biblical times. At its other end, 100 ft. away, Yadin saw water sparkling in the torchlights. Instead of depending on springs, Ahab's engineers had dug deep...
