Although the contractors had shipped excellent spacecrafts, preparations at Kennedy did not go quickly from the assembly building to the launch pad. Testing was delayed several days in order to stay out of the way of Apollo 9 pre-flight activities. Also during maintenance to the Launch Control Center, the electrical power was switched off to replace a valve. The Apollo 10 launch vehicle’s pneumatic controls sensed the power outage, opened some valves and dumped 20,000 liters of fuel on the launch pad.
Even before crawling back into the command module, McDivitt said he was tired and ready for a three-day holiday. Another 140 hours would pass before touchdown in the Atlantic, but the crew had achieved more than 90 percent of the mission objectives.

On the fourth day of the flight of Apollo 9, Schweickart felt better than expected as he worked his way into the lander to get it ready for the EVA. By the time he had put on the backpack, McDivitt was ready to let him do more – to stand on the lunar lander porch at least.

As Dave Scott pulled in closer to the Lunar Module he noticed that the command module’s nose was out of line with the lander’s nose. Scott tried to use a service module thruster to turn left, but that jet was not operating. It turns out that someone had accidentally bumped a switch that turned off one set of Thrusters. The crew then flipped the correct switches, and the thruster started working, and at T+3 hours 2 minutes the command module probe nestled into the lunar Module drogue, where it was captured and held by the 12 latches. The first docking of the Lunar Module in space was achieved. As a side note, switch guards were installed on all future Apollo missions to prevent accidentally flipping a switch.

For the 19th flight of American astronauts into space, Vice President Spiro T. Agnew, representing the new administration of Richard Nixon, sat in the firing control room viewing area on March 3rd, 1969. He and other guests listened to the countdown of the Saturn-Apollo structure several kilometers away at the edge of the Florida beach.

James Alton “Jim” McDivitt was born on June 10, 1929, in Chicago, Illinois. He is of Irish descent. Like many other astronauts, he was a Boy Scout and earned the rank of Tenderfoot Scout. He graduated from Kalamazoo Central High School, Kalamazoo, Michigan, in 1947.
