I just spent the last several months putting together a war documentary which includes the Case SI Airborne Tractor and how it was flown in behind enemy lines in Waco Gliders to help build air strips during WWII. I'm hoping to produce another documentary that goes more in depth on this tractor and the men who used them. Any information you guys have would be very helpful. If anyone is interested in the documentary I just finished, please check out www.agelessirontv.com. Thanks in advance for your help. Rod Reding.
