Within 20 minutes of the the video, I had this list of items throwing up red flags in my head:
1. End of Shift
2. Long Work Hours
3. Inadequate Sleep Patterns
4. Wrong Parts Causing Work Delays
5. Young/Inexperienced Workers
6. Unfamiliar/New Work Instructions
7. Failure to Follow Work Instructions
8. Wrong Tool For the Job
9. Dropped Objects
10. Delay/Slow to Report Issues
11. No Plan For Worst Case Scenario
Any of those sound familiar?
Overall I'd say it's a pretty good documentary even though it does jump around a bit. A bit heart wrenching listening to the personnel involved telling their accounts of the event and how it affected their life afterwards.
