These are great photos. I understand why you feel like they are soulless, but you are photographing something very challenging... plus, while the pilot is a big part of the story, the planes takes all the glory. (...apparently I'm poet!). Of course, also part of the story are the the observers on the ground and the world around the plane and pilot. It's not easy to capture what I think you were hoping to capture, but you have to start somewhere and you did a really great job with these.
Wonderful photos and I really like what you tried to do with the flag one.
