Latest on spent fuel pool cooling attempts, Daiichi

As noted earlier, the helicopter drops focused on No. 3 plant only. Experts are saying that the effort appeared fairly ineffective; THIS writer agrees. Only the first shot (I watched all of it live) seemed a direct hit.

There was a very brief mention during one press conference, not repeated anywhere since (but I caught it) that there was a spike in suppression chamber pressure at the time of the drops. The implications of this are numerous but also might simply have been the direct impact of over seven tons of water on the structure and area with that first (lowest, most direct) water drop. Pressure may not have spiked; the detector may have been jarred, in other words. All speculative.

The water cannon vehicles have not yet entered the site so far as can be determined.
