A PRIL - M AY 2012 HONORING AMERICAN MILITARY AVIATION THROUGH FLIGHT, EXHIBITION AND REMEMBRANCE FAR FLUNG ATHWARTSHIP By Col Denis Godfrey The aircraft catapult launch has long been the Navy’s E ticket ride. Now imagine that same launch from inside a dark tunnel and as you emerge airborne; blinded by daylight and blasted with a 20 knot crosswind upon your battle loaded Hellcat just 30 feet above the waterline, adding P factor (pucker) to the E ticket experience. This was the sequence of events for pilots launched from the HIVA, athwartship, hangar deck catapult. Athwartship catapults had been around for years prior to World War II, installed on battleships and cruisers to launch patrol aircraft. Prewar, aircraft carrier doctrine was in flux and many ideas for aircraft ops emerged. As newer, monoplane aircraft with increased ordnance loads were entering service, the need for catapults on aircraft carriers was recognized. Hangar deck catapults were proposed with the reasoning that aircraft could be launched below and trapped above at the same time. It would also negate moving aircraft to the flight deck allowing aircraft to warm up on the hangar deck and then launch directly from there. It was envisioned that scout planes could be launched from this position too without disturbing the aircraft arrangement on the flight deck. Also, most early carriers did not have catapults and instead, arresting gear was installed aft and forward on the flight deck as a redundancy. If the aft end of the flight deck was battle damaged, they would simply steam the ship backwards and utilize the forward gear! Installation of a catapult might interfere with this arrangement. pult but could still be utilized in concert with whatever ops were occurring up top. This arrangement was adopted into the Essex class aircraft carrier design and Intrepid, Wasp, Hornet, Yorktown, Bunker Hill and Franklin, were to have hangar deck catapults installed adjacent the forward elevator. To achieve the required length across the hull for a catapult shot, sponsons with folding outriggers were installed on each side of the open hangar deck. Eventually what developed was one flight deck and one hangar deck catapult, both hydraulically actuated. The latter serving as backup for the primary flight deck cata- A Hellcat being prepared for catapult launch aboard Yorktown displays the overhang of the sponson and outrigger from the hangar deck.

After many hours of calls, negotiations and frustration your show scheduling team has put together a 2012 Air Show Schedule for our Wing that includes a couple new shows for us to visit and some reliable regular annual stops. Shown here is the schedule of confirmed shows with one that frequently appears but never seems to come to fruition in El Paso, TX. Of course CAF AirSho in Midland, TX is not much of a fundraiser but helps keep the CAF in the spotlight. Shows in Powell, WY and Elko, NV provide the opportunity to show our TBM to new crowds - always a pleasure. In fact that’s what it’s all about. Best Laid Plans... It seems that our Air Show schedule is in a race to see if it can melt away faster than this years western slope snow pack. Despite continuing efforts by Cols Thompson and Godfrey we’ve had several cancellations - the most disappointing to date our first 2012 scheduled appearance at Davis Monthan AFB in Tuscon, AZ. It seems that the expected fuel reimbursement went away and then the opportunity to operate our PX was in question (something that occasionally happens at military air shows). The end result was that attending the show was guaranteed to cost the wing money. It’s tough enough trying to stay ahead of our costs to attend these shows so a known loser is just that - a loser. All that effort by Col Marvel’s Wicked Wrench Wranglers to have ‘309’ ready to attack the air show season at this planned first show will not be wasted though. Read Col Marvel’s Maintenance Report on page 3 to learn how those guys never rest. ed. Wing Public Information Officer Col Denis Godfrey took this aerial photo of the CAF hangars at GJT. Col Marvel’s Wicked Wrench Wranglers are huddled around ‘309’ after all that winter maintenance. The puddle under the engine is just that - a puddle of water from washing the engine area to make little seeps and drips easier to find. The work for those guys never ends. Is that east hangar bent? A PRIL - M AY 2012 HONORING AMERICAN MILITARY AVIATION THROUGH FLIGHT, EXHIBITION AND REMEMBRANCE P AGE 3 Maintenance Report - Missing Show Leads to Missing Parts By Col Bill Marvel Maintenance Officer To no one’s surprise (or so I hope!), all work on the TBM, including several inspections, was complete and signed off in time for our first show of the season in Tucson. Well, as you have read elsewhere in this issue, the USAF changed the terms of the contract at the last minute, resulting in our decision not to fly the airplane there. The back and forth costs would have exceeded any possibility of our even breaking even given the financial restrictions imposed on us. As a result, we took time before the Tucson weekend to do further tweaking on the airplane to reduce the hydraulic pump output pressure by a couple of hundred psi. That went well as did another test flight. The oil leaking number 9 cylinder discussed in the last issue is still living up to its namesake. As to the serial number discrepancy between that cylinder and the paperwork which came with it, one has to ask if the work was done on our cylinder and the paperwork was incorrect, or if the paperwork was correct and the work was done on a different cylinder. You can flip a coin on that one and either side of it is equally valid. What you can’t flip a coin to dispute is this -- the cylinder passed hot and cold compression checks, a visual inspection, an operating temperature check and a valve guide wobble check, so there is little more to do than accept the oil leakage and fly the airplane. And that is what we are doing. After all, it is an upside down cylinder in a radial engine and that is a recipe for throwing oil. I, for one, believe many of the TBM’s problems are occurring because of too little flight time and not too much. Cost or not, airplanes need to be flown. Two small problems were noted during inspections and I determined they were not airworthiness issues in the short term. Both were deferred for future resolution once we had a break in the air show schedule. Curiously, they involved hydraulic leaks-- does that surprise anyone? One was in the right wing and the other in the tail section. More specifically, the right wing flap sequence valve had a minor leak as did the tail wheel retract cylinder. Neither was an operational issue at the noted rate of leakage but when the Tucson show cancelled, I decided to use the newly available time to remove both components for repair. As of this writing (April 18), they are in Idaho and will be returned to us shortly for installation in the airplane. Once that is done, I suspect the irritating but small telltale puddles of red hydraulic fluid on the hangar floor will be replaced by the much more preferable dirt and dust. All in all, the airplane is in the best shape in years and should be ready for the rest of what is already a disappointingly short show season. . The missing right flap sequence valve used to be here, connected to the two aluminum tubes. The missing tail wheel retract cylinder was once attached to the two flexible black hoses you see.

The government is tightening its belt everywhere, and we are down to only 10 shows on the schedule now for this year; we are looking at other ways now to raise funds so we can ‘keep ‘em flying! As I mentioned last month, we are planning a local open house, showcasing our aircraft and museum to the Grand Junction and western Colorado community. We’ll use it as a fundraising opportunity, selling rides in the TBM and Cub, but most importantly, we’ll use it as a recruiting venue, hoping to bring people in who are interested in what we do and want to help out. Please plan to help us get more volunteers in to our group! We still haven’t set a specific date, but in order to get our facilities spruced up and have time for sufficient publicity, it will probably be held on a Saturday in early June. Due to the cancellation of the Arizona show, our first air show will now be on Memorial Day weekend at Hill Air Force Base in Ogden, Utah. Be sure to sign up to crew this show if you’ve got the weekend free! And, even though we’ve had a few cancellations, we will still be attending many shows this summer and we can use your help. Be sure to check the board in the hangar and sign up now to help out. Thanks again for your help to “keep ‘em flying.” January 21, 1945 The Deck of the Hancock shortly after a VT-7 TBF Avenger was trapped aboard and while taxiing with two 500-pound bombs in its bomb bay the pilot, not knowing that he had armed bombs hung up in his Bomb bay.. opened his Bomb bay doors; the bomb falling to the deck and exploded. http:// www.usshancockcv19.com /history.htm A PRIL - M AY 2012 HONORING AMERICAN MILITARY AVIATION THROUGH FLIGHT, EXHIBITION AND REMEMBRANCE RMWCAF STAFF OFFICERS Wing Leader Collin Fay Executive Officer Bruce Verstraete Finance Officer Don Coleman Adjutant Jerry McDonough Operations Officer Rob (Dunc) Duncan Maintenance Off.

Savoia-Marchetti SM 79 Sparviero It sounds incredible, but SM 79 actually caused more allied war and merchant ship losses in the Mediterranean than Italy's entire surface navy! Courageously flown, it was a considerable thorn in the side of the Allies in the Mediterranean theater until overwhelmed by Allied air superiority. Says something about the Italian Navy, eh?

Therefore, the hangar deck catapults were abandoned in short order and the Navy later removed them and on some carriers, added a second catapult to the flight deck. The Hornet was the only carrier that retained and utilized its hangar catapult till the end of the war. The catapults took up a lot of valuable real estate on the hangar deck and found not to be all that useful. The need to launch scout planes was ren- The popular science fiction TV series of the late 1970’s, Battlestar Galactica, often featured Lieutenant’s Apollo and Starbuck being launched Buried Treasure - Warbird Style Aviation historians and warbird enthusiasts are drooling at the discovery of at least 12 and maybe as many 20 perfectly preserved brandnew Spitfire Mark 14s buried in Myanmar, which was formerly Burma. Thanks to the tenacity (and apparently considerable diplomatic skills) of British farmer David Cundall, the lost squadron of pristine fighters was found where they were buried by U.S. troops in 1945 when it became clear they wouldn't be needed in the final days of the Second World War. At least a dozen of the aircraft, one of the latest variants with their 2,035-horsepower Roll in their Viper fighters athwartship, zooming out the side of the battlestar. Whiz bang Hollywood stuff for the youngsters in the audience but something familiar to many WWII aircraft carrier veterans. But like so many Hollywood fantasies, the hangar deck catapult was a whiz bang concept made impractical by the realities of evolving aircraft carrier operations.

Royce Griffon engines replacing the 1,200-1,500horsepower Merlins in earlier models, were buried without ever being removed from their original packing crates. It's possible another eight were also buried after the war ended. After spending 15 years and $200,000 of his own money, Cundall was rewarded with visual proof of the magnitude of his discovery. "We sent a borehole down and used The aircraft were declared surplus when they arrived in Burma because the Japanese were in retreat by then and carrier-based Seafires were getting all the action. They were ordered buried in their original crates, waxed, swaddled in grease paper and their joints tarred against the elements. Cundall found some of the soldiers who buried the planes by placing ads in magazines and was able to narrow down the search before using groundpenetrating radar to confirm the burial site. The next obstacles to recovery are political. Myanmar's former military junta was under a variety of sanctions, among them an international convention that prevented the transfer of military goods to and from the country. Recent political reforms have led to the lifting of that ban effective April 23. Cundall will also need the permission of the new Myanmar government to unearth the treasure.
