I'm going to cheat today and cover both of the "What's special" shots from earlier this week in one post. Lots of you guys had ideas for the first shot (above), including what I saw: This was the first time I can remember seeing three B777-300s side-by-side at Terminal Two. It's a daily occurrence to have two B777s, most often at gates 21 and 25. Other times, we'll have a pair of B777s at 21 and 23, with an A340 at 25. Also noteworthy, as several of you noted, is the Air Canada B777 - which is not a normal Air Canada aircraft at LAX.
A number of you figured out the second photo as well. It was a lucky shot early one morning last week; if I hadn't been in the tower at the time, I would've missed it because the opportunity only lasted for about ten or fifteen minutes. What's happening here is a test-fitting of a US Airways A321 at Terminal Three's gate 31A; so far as I know it was the first time that an A321 has been put on that gate. Prior to this point, all the carriers who've been at gate 31A have used B737s (Alaska), A320s (Frontier, JetBlue, Spirit, and Virgin America), or MD-80s (Alaska and Allegiant). A few days later, US Airways moved from Terminal One to Terminal Three. Here is another sunrise shot, showing US Airways Airbuses at gates 30, 31A, 31B, and 32:
