- How are you?

- Very fine, thank you. Never was better.

- Sit down, Mr. Jackson.

- Just how would you describe the man you saw on the observation platform?

- Well, I'm pretty sure he was a younger man... about 10 or 15 years younger than the man in these photographs.

- Dietrichson was about 50, wasn't he?

- Fifty-one, according to the policy.

- The man I saw was nothing like 51 years old.

- Of course, it was pretty dark out on that platform.
