Short answers, pulled from the story.
AS-101, also designated SA-6, was the sixth flight of the Saturn I launch vehicle and the first to carry a boilerplate Apollo spacecraft. It launched from Cape Kennedy Air Force Station on the 28th of May 1964.
BP-13 was a dummy Apollo spacecraft that duplicated the size and shape of the real command and service module but weighed 17,000 pounds, roughly 5,000 pounds more than a flight-weight command module. It was instrumented with 116 sensors measuring strain, pressure, temperature, heat flux, and acceleration.
Engine number eight shut down at 116.9 seconds after liftoff when the teeth on a turbopump gear were stripped off. The rocket's guidance system compensated by burning the remaining seven engines for 2.7 seconds longer than planned.
AS-101 completed 54 orbits in total. The spacecraft reentered the atmosphere east of Kanton Island in the Pacific Ocean on the 1st of June 1964.
The first attempt was scrubbed after liquid oxygen damaged a wire mesh screen, causing fuel contamination. The second was scrubbed when an air conditioning compressor failure caused the guidance system to overheat. On the third attempt, a theodolite was obscured by liquid oxygen vapors, but engineers reprogrammed the computer to proceed without the reading.
AS-101 was designed to verify the launch aerodynamics of the Apollo command and service module and its launch escape system tower. It was followed by four more Saturn I flights for the same purpose before NASA progressed to crewed vehicles.
