OK, I've been at the airport a -lot- this week, and I have two curiosities. I tried to search for these answers and couldn't find anything.

I'll probably look foolish or uneducated by them, but I'll sleep better (or be ready for Who Wants to be a Millionaire) with the answers.

1) Who is the guy on the tail of Alaskan Airlines planes?

2) Why did Delta switch their livery twice in the last few years...and why does the newest version not have the name or logo on the tail (unlike most other US carriers)?

Thanks.
