As many readers will be well aware, there are a number of Boeing B-17s under restoration to fly right now. Perhaps the boldest of these projects is Mike Kellner’s effort in Marengo, Illinois. He and his team are working to resurrect Boeing B-17E 41-2595, a combat veteran Flying Fortress which once bore the nicknames Desert Rat and Tangerine. As we have reported previously, Kellner found the aircraft in a farmer’s field near Bangor, Maine as a collection of chopped-apart components back in the mid-1980s. Somehow, he had the vision to see this jumble of battered parts one day going back together again as an airworthy B-17. The project got underway in earnest during the mid-1990s. While Kellner and his intrepid volunteers work on a shoestring budget, they have engineered miracles with their efforts; the Fort’ is well on her way to becoming whole again. Interestingly, the aircraft did not serve as a bomber during her combat life (in the China Burma India theatre), but rather as a converted cargo plane prototype for the breed known as the XC-108A. Despite this unique aspect to the airframe, Kellner is restoring the aircraft back to its original B-17E configuration, to the way the airframe would have looked when it rolled off Boeing’s production line in Seattle, Washington during April 1942. Desert Rat, as Kellner and his team have re-dubbed her, will be the oldest Flying Fortress in the skies when she finally flies, although this record may eventually be surpassed by a B-17C which the team also has on the books. Desert Rat could use our help though, but before we provide a link for contributions, we thought our readers would enjoy a recent visit by Scott Thompson of Aero Vintage, we have permission to relay his latest article on the project, reproduced (with gentle editing) below.

The restoration crew at Marengo, Illinois, working to restore B-17E 41-2595 (otherwise known as Desert Rat) continues to make steady, if slow, progress on the challenging effort. For those not familiar, this rare B-17E was recovered from a remote farm in Maine way back in 1985 by current owner and team leader Mike Kellner. It was in terrible shape, having been subjected to an unsuccessful but damaging attempt to scrap the bomber. Now, jump forward through four decades and the airplane is slowly coming back together in airworthy condition in a purpose-built building in rural Illinois.

The restoration started in earnest around 1993 or so, and the first and most ambitious challenge was to structurally rebuild the fuselage after it was cut into pieces earlier by those seeking to turn it into scrap. Also, there was a large, non-standard fuselage cargo door added when this particular B-17E was modified by the AAF to become the sole XC-108A, and that cargo door had to be removed and the structure replaced. This structural work required manufacturing many new and specialized longerons and formers to replace those cut, and jigging the fuselage so things would line up properly. All that work on the fuselage structure was completed several years ago.

The all-important carry-through structure that holds the wing attach fittings and girdles the bomb-bay is the last major structure of the fuselage that awaits completion. Most of the custom-made parts are now on hand so it is a matter of carefully assembling the structure back into the fuselage.

For those who have watched the effort in recent years, progress is not readily apparent but, in fact, much work has actually been accomplished. In particular, the complex airframe structure around the ball turret is completed, as is most of the restoration of the camera bay located forward of the ball turret and aft of the bomb bay. The work effort by Kellner and his all-volunteer crew is now focused on the important carry-through structure in the bomb bay which consists of, among other parts, the wing attach points. New steel tubes had to be extruded to exact Boeing specifications and carefully installed in place of the old, unairworthy tubes. This is exacting work because the tubes hold the terminal fittings that will mate to the B-17 inner wing sections. Being off an eighth of an inch just won’t fly later when trying to attach the wings. As the photos show, new terminal fittings on the fuselage side are being installed. Most of the components to complete the bomb bay section are now available, and the parts are being fitted and riveted back into position. After the carry-through structure is completed, the bomb bay catwalk is built and ready for installation. After that, it will be bomb racks and bomb bay doors plus the actuating mechanisms…the list, it turns out, is pretty much endless.

The right forward fuselage side wing attach fittings are in position and will soon be permanently riveted back into the assembly.

After the fuselage structure is completed, the cockpit area will need to be reinstalled. At some point in the future, the electrical and other systems will need to be recreated and installed as per the original Boeing specifications. The wings recovered from the field in Maine are eventually going back into this airplane. They have received some work, but attention has primarily been on the fuselage over the past few years. One of the wing’s inner sections has been stripped out for cleaning and evaluation. The two outer wing panels have had the skin removed in jigs and will be reskinned as time allows. There are four engines present, but all four will need overhauls, as will the propellers.

A beautiful instrument panel complete with all the instruments is in storage and ready to be installed at the appropriate time. Components for the operable top turret are being assembled offsite. The top turret dome rests in place on the fuselage.

As can be seen, this restoration effort remains a monumental task. Mike Kellner and his small volunteer crew are devoted and spend many days each week working on the small pieces that gradually become the big pieces. As in any such restoration project, finances and labor are the challenges. If you live in the area around Marengo, Illinois, which includes the greater Chicago and Rockford areas, and have some talent, experience, or just enthusiasm, Mike would like to talk to you. Perhaps contact Mike via email. Many parts have to be created from drawings or pattern pieces, so someone with that skill set would be ideal.

The three dedicated workers on the morning I showed up were, from left, Bill Stanczak, Chris Gibson, and project manager Mike Kellner.

Desert Rat also has its own dedicated Facebook page HERE which some of our readers may enjoy viewing too. If you wish to contribute to the restoration of this important aircraft, whether it be with parts, labor or cash, please contact the Desert Rat team HERE. Monetary donations can be placed HERE.

Many thanks indeed to Scott A. Thompson for allowing us to reproduce this article describing Desert Rat’s present condition… his book, Final Cut: The Post-War B-17 Flying Fortress and Survivors as well as other titles are the gold standard when it comes to the airframe history it describes!

  1. Cool project in area I was born. Belvidere. Lived in Garden Prairie too as kid. Best wishes for success

  2. Retired from aviation and have some Sheetmetal tools that I would like to donate to a B-17 restore effort. Dad was left seat in 1944 and was shot down, spending 16 months in a German prison camp, so it’s personal for me. I have bucking bars, micro counter sinks, rivet gun, gloves, hand squeeze sets, lots of rivet sets, etc. Would supply pictures to see if you could use or not. Need a prepaid box to send them to you in.

  3. Incredible awesome unbelievable b17i am going to talk to some companys who I think would love to help you with the money and resources to help you get her in the air
