OK folks, here's an update for the C130. As I suspected, the military are not keen to disclose arrival times of their aircraft. Dunno why, but that's how it is. We'll have to keep our eyes 'n' ears open for any EAA announcements and hope that we're in the right place at the right time. Here's a copy of the response:
"Dear George, thank you for your message. I was not sent a show schedule and unfortunately we don’t give out arrival times of military aircraft. I would visit the airshow website or inquire when you get there. I wish I could be of more help. I hope you get the photograph you are looking for. Best of luck!"
