The official story is that NASA skipped testing the all-important Lunar Module on which the lives of the "astronauts" depended. Was the head of NASA a murderer or a faker?

The first unmanned LM flight was planned for April 1967, but because of development delays did not occur until January 22, 1968 when the Apollo 5 flight launched the LM-1 atop a Saturn IB for propulsion systems testing in low Earth orbit. A second unmanned test flight of LM-2 was originally planned, but canceled as unnecessary
The first manned LM flight was also delayed, planned for Apollo 8 in December 1968 but not occurring until Apollo 9 using LM-3 on March 3, 1969 to test the LM's systems, separation and docking in low Earth orbit. Apollo 9 had been planned as a second manned, higher Earth orbit practice flight, but this was cancelled to keep the program timeline on track
Apollo 10, launched on May 18, 1969, was a "dress rehearsal" for the lunar landing, practicing all phases of the mission except powered descent initiation through takeoff [i.e., what it was actually supposed to do]
. The LM descended to 47,400 feet (14.4 km) above the lunar surface, then jettisoned the descent stage and used its ascent engine to return to the CSM.
If an engineer actually wanted a successful mission without murdering the passengers, he would demand thorough testing of the single most critical component.
On the other hand, if an evil engineer wanted to fool the public with an inadequate crucial component, he would deliberately minimize public testing of that component so as not to make its inadequacies obvious.
