...recovery site in the Pacific, a frogman dressed in an all-enveloping biological insulation garment (BIG) will open the command-module hatch, toss in three similar garments and quickly close it again. Inside the Apollo cabin, the astronauts will don and seal their BIGs before reopening the hatch and stepping into a pool of antiseptic at the bottom of an adjacent rubber raft. Almost immediately, the frogman will again close the hatch, spray antiseptic around its edges, and then give the astronauts themselves a thorough spraying...
...their suits, the astronauts will be effectively prevented from contaminating the atmosphere. When they inhale, air will be drawn into their BIGs through a one-way valve; the air they exhale will be vented through a biological filter designed to block the passage of tiny organisms. Conversely, the frogman will be protected by a biological filter to screen the air that he inhales. Some scientists fear that these elaborate precautions-and those that follow-could be negated during the two brief intervals when the Apollo hatch is opened; alien organisms inside the spacecraft could take these opportunities to escape into...
...Pacific, the crew will have vacuumed the interior, collecting the swept-up material in canisters containing a chemical absorbent. Instead of climbing through the command module's open hatch and into a raft before donning their biological isolation garments, the astronauts will remain inside the spacecraft until a frogman opens the hatch, tosses the garments inside, and then closes it again. They will change into their bug-containing outfits and step into a raft filled with disinfectant. Then the frogman will spray more disinfectant on the astronauts and around the spacecraft hatch...
Deciding to trade one risk for another, NASA, without fanfare, changed its recovery plan. While Apollo 11 is still in the ocean, the hatch will be opened. As the astronauts emerge and climb aboard an attached raft, each will slip into a "biological isolation garment" brought along by a frogman who will be similarly outfitted. The suit is equipped with a filter that should block any organisms that the astronauts exhale. After a helicopter ride to the carrier deck, they will enter the van and follow the original quarantine plans...
...quiet moonlit night. The blast slammed the Greek tanker Eleftheroupolis against its pier near the Nha Be tank farm southeast of Saigon, Despite the constant allied watch on shipping along the entire 30-mile length of the Long Tau channel, which links Saigon and the sea, a Viet Cong frogman had attached a 100-lb. charge to the vessel's anchor chain. Damage was minor: one compartment was ruptured, but the jet fuel inside did not ignite...
