Terry & Rob-
I just spoke with Alan Toelle & he would be very interested in any information you'd be willing to share with him on the 27th A.S. He was the editor of OTF I mentioned above.
Alan also wanted to know if you'd be willing to share more of that McCubbin diary with him.
Alan has my utmost respect. He has been researching WWI Aviation well before I was even a twinkle in my Dad's eye. Alan is also a renowned expert on the SPAD & Breguet aircraft, with many published books & articles to his name. He mentioned he'd be more than willing to share data with you both if you should contact him. Please take this opportunity to email him directly. I know he'll be looking forward to hearing from you both, or from any other member who's willing to share information about the 27th Aero Squadron.
Here is his email address (posted with his permission of course!):
