This is my quote of the day. I wish you hadn't posted AC.
The number of unrecovered black boxes is pretty damn low: in the past 25 years, only one airplane's recorders were lost. The rest were either destroyed in the crash, or deliberately not recovered.
I'm sure a "very clear explanation" is given, but I'm not going to read something that presents it to me at a rate of one sentence per page.
The author is correct, but he expressed it in a very awkward way: below Wanapum Dam is Priest Rapids Dam, and below that is the Hanford Reach, a free-flowing section of the river. If Wanapum fails, the Priest Rapids reservoir needs to absorb the entire flood; releasing it will cause flooding in the Hanford area.
