The information that the TN S1 shaft was only 120 m deep is even more worrying. This is because there was no crater in S1 while the 25 kt A bomb created a 25 m diameter crater at S2. I am assuming that the S2 was about 100 m deep. The implication is that the S1 TN yield must have been considerably less than 25 kt. I don't see why Santhanam and ARC are saying that the S1 yield was 20 kts when there was no crater and the A-frame was intact in S1.
This adds to the puzzle!
