Tim Chopp is the President of the Berlin Airlift Historical Foundation. Tim has been unbelievably generous to my museum, donating two Boeing C-97 QECs with Pratt & Whitney R-4360-59B engines and multiple batches of additional parts to make a complete QEC for display. Tim is one of the most remarkable people I have ever met, with boundless knowledge, experience, energy, and enthusiasm for spreading the history of the Berlin Airlift through operating the Foundation's Douglas C-54 at aviation events all over the country and Europe. Their Boeing C-97 has now flown several times after a lengthy restoration and is the only flying C-97 in the world. Many thanks to Tim and all of his incredible volunteers. I have an additional page with more information on their mission. Tim Chopp is on the left in the first photo with C-54 copilot Scott Szuhay in my Douglas C-118 cockpit. Photos below show one of the C-97 QECs after about 1,000 hours of restoration work.
