How close was the mission to being aborted during the launch phase as a result of the second stage center engine shutdown?
Would the early shutdown of the engine increase the g forces or the pogo oscillations on the crew to a dangerous extent? Most accounts play down this part of the mission as a minor hiccup.

It wasn't close to an abort and the g loads were reduced by 20%. It would negate any pogo effects since the thrust was reduced. Margins were reduced due to the lost of the engine but that is what happens when you lose redundant systems.

That's what I thought but John Young made it sound more dramatic in his book.

If it wasn't for the "major hiccup" two days later, the second stage issue may have received more attention.

It's interesting that Young discusses it in his book because Jim Lovell in 'Lost Moon' doesn't mention it at all. It was in the movie 'Apollo 13' but not in the book (at least the original 1994 edition). I've always thought it very odd that that 'glitch' was left out of 'Lost Moon'.
