Unreasonable effort

I went to bed certain that our 180 second vehicle was dead. We split the tank over 20 inches of the main seam. My son and our welder Bob would not give up they got up at 6 am and spent the day grinding bending and otherwise beating the tank back into shape. They then re-welded the bad seam. At 2:30pm this afternoon it passed Hydro. Its clear that we are real close with little margin, but we do not pressurize in the presence of humans so even if it failed we would not hurt anyone. This was a 12 hr detour that we did not need. Its still a Hail Mary to be ready for the 180, but we are not yet dead.
