When we weren't busy catching our breath from running to make planes, Alex was chatting up every pilot he came across. He was invited into the cockpit on 3 of our 4 flights. On one, they let him push the "ding" button (everyone had deplaned at this point). On the last flight, he was not only allowed in, but the pilot let him sit in his chair, adjusted the seat so he could see out the window, and let him wear his hat. (He also encouraged me to take pictures.) Alex was over the moon excited.
(Wow. Post number 400.)
