Splashdown

"Splashdown" is the 90th episode of Gilligan's Island and the 22th episode of the Third Season. It aired on February 20, 1967.

Synopsis
The Professor tries contacting a manned space capsule in orbit over the Island the get them rescued. Their initial plan to contact the capsule with a makeshift radar fails because their signal isn't strong enough, but their second plan to contact the astronauts with an SOS formed out of tree trunks almost works until Gilligan sets himself on fire and accidentally skews the SOS into "Sol." Astronaut Sol Tobias merely thinks its a message to him. On the last trajectory, however, the experimental space capsule drops out of orbit and lands on the Island. The castaways decide to use it to float to safety, but they don't know is that the capsule is set to self destruct by NASA to conceal its records. The Howells and the girls both try to stowaway in it with Gilligan and the Skipper going off to get help, but they get discovered, delaying the rescue attempt. As the Professor chides them for their selfishness and dangerous stunt, the capsules floats off into the lagoon where it finally explodes, showering the island and the castaways with wreckage. Mr. Howell, however, fails to take the failed rescues with grace. After losing money and brandy in the botched rescue attempts, he has a temper tantrum and tearing apart his hut, stopping just short of destroying his teddy bear.

Trivia

 * When Ginger is found out trying to stow away on the capsule, she stars her sentences "Would you believe..."? This phrase echoes Agent 86 Maxwell Smart of Get Smart who also stated silly sentences this way.
 * The castaways try to get help three times: first, by sending a weak radio signal which goes through but fails; second, by lighting logs signaling "S.O.S" until as usual Gilligan ruins everything and then three, they try to use the space capsule.
 * The part where Gilligan fouls up the rescue by turning "S.O.S" into "S.O.L" is similar to the "Pilot" epsiode when the castaways try to spell out "S.O.S" to a passing plane and Gilligan again messes up the last letter {which are written with fish!}
