How could the Apollo 13 problems have been avoided?

The Apollo 13 problems could have been avoided through more rigorous testing and quality control of the spacecraft's components, particularly the oxygen tanks, which were known to have design flaws. Improved communication and oversight between different teams involved in the mission might have ensured that critical safety concerns were addressed. Additionally, adhering to stricter guidelines and protocols during the pre-launch phase could have helped identify potential issues before the mission commenced. Finally, a more conservative approach to modifications in the spacecraft's design could have minimized the risk of failure.
