A duplicate of the famous helicopter that plucked the Apollo 13 crew, as well as Apollo 8 & 11, on display in San Diego, California. The original later suffered an engine failure and crashed into the Pacific Ocean.

The evidence of what went wrong was in the telemetry from the second the explosion occurred . 'Main B Bus undervolt' as reported by Jim Lovell was the first clue. So Fuel Cell B had a problem. Telemetry received at Houston confirmed it in more detail. Plus the pressure from the associated tanks were dropping rapidly and other hardware located next to it began to fail also. They were the first indicators of the cause.     More detail in the revised book.


The evidence is for all to see; no mystery if one bothers to research it properly rather than guess and embarrass yourself as Marcus constantly does. He never admits he is wrong about anything and hope you never bother to research it yourself. 

apollo 13 investigation

If you desire the full explanation of what happened and how the investigation was carried out in more detail than my book; this Haynes Manual is perfect. 

One particular hoax supporter, Marcus Allen, points out that without the Command Service Module (CSM) in a laboratory, how could NASA possibly understand what caused the explosion that called off the Lunar Landing?
