There were 10 people total. The ADN headlines reported what they knew for a fact at the time, three people survived, three people were found dead  and four were still missing. 
I just bought the book yesterday and I was going to start reading it but my husband grabbed it away from it. It is a very sad tragic story but his mother who was 16 at the time survived and later gave birth to him at some point in time. He grew up to be a pararescue man and saved many lives. I can wait to read the book.
