McDivitt later said that the engine had come on abruptly, but with the tremendous mass, acceleration was very slow – it took the whole 5 seconds to add 11 meters per second to the speed.

Space Rocket History #180 – Apollo 9 – Lunar Module Maneuvers

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.
