RL, Where did you find the pictures? Is there any story to go with them?
Lieutenant Commander Syd Bottomley, who had earlier served as XO of VB-3 at the Battle of Midway and then succeeded Max Leslie as squadron CO when Leslie fleeted up to CAG-3, was assigned to the Ship Experimental Unit of the Naval Aircraft Factory at Mustin Field, Philadelphia in the fall of 1943. The SEU was responsible for the evaluation and testing of catapult and arresting gear engines and associated handling equipment designed for shipboard and small field use. Bottomley was charged with the operation and maintenance of the test aircraft assigned to projects by the Bureau of Aeronautics and preparation of test aircraft reports, including evaluating carrier suitability portions of the Board of Inspection and Survey trials of new prototype aircraft. Assisting him were Lieutenants Bob Elder and Charlie Lane who had served with him in VB-3 and whom Bottomley dragooned away from the training command.
Among the projects under Bottomley's charge at SEU were the modifications of the P-38, P-39 and P-40 with catapult hooks by NAF for launching from jeep carrier transports. After modifications were completed it was Bottomley and company's place to make catapult shots to determine feasibility, trim tab and flap settings and check flight characteristics. Soon they were also given a modified P-47, P-51, and even a P-61 for catapult feasibility testing. The Bureau of Aeronautics already knew that B-25's could be launched from carriers, but wanted to know if they could be launched with catapults and so provided SEU with a Marine Corps PBJ-1H (BuNo 35277) which the Corps had acquired from the USAAF. The PBJ-1H was the same as the cannon armed B-25H, and, indeed, this particular airplane had started its life as USAAF 43-4700.
Much of their activities involved testing the tricycle landing geared Grumman F7F Tigercat. No tricycle gear aircraft had ever been in carrier service and there was great concern over possible fuselage and nose damage resulting from the stress of off-center landings with a fixed, non-swiveling tailhook. Charlie Lane was project pilot and lost no time in demonstrating what an uneven cable friction load could do to the skin and frame of a nose-wheeled airplane. It was apparent that the arrestor hook needed to be relocated further forward and have swivel capability if the F7F was to ever carrier qualify. To further prove their points of hook location and swivel, Bottomley sought and received permission for BuAer to include their PBJ-1H in catapult and shipboard handling tests. An SBD tail hook assembly(the SBD was considered to have the most reliable tailhook arrangement) was installed on the PBJ and it was readied for further testing. In land based tests conducted at USCGAS Cape May an unexpected problem appeared: with full-flight engagement of the arresting gear, the single pilot's seat lock would disengage and let the pilot and seat slide forward onto the yoke. This was a big surprise the first time it happened and certainly not a happy event for Bottomley. As a solution, a steel strap was welded to the top of the seat from the bulkhead behind the pilot to keep the seat in place.
On November 15, 1944, three aircraft were successfully tested for arrested landings and catapult launches aboard USS Shangri-La. Charlie Lane successfully demonstrated the results of relocating the swivel arrestor hook on the F7F. Bob Elder put an arrestor hook equipped P-51 through its paces.
And then it was Bottomley's turn in the PBJ. Bottomley told the story:
" . . . it was amazing how easily the PB| swung into the groove and picked up a wire. The ensuing catapult shot was a breeze, as was the next landing. Then the PBJ was struck below for handling tests on the hangar deck. The main wheels had been designed to turn sideways to ease the plane into tight spots, so BuAer and AirLant staff observers were all over, in and under the PBJ.
"Everything had gone so well it was determined no further shipboard tests were necessary and I taxied into position on the catapult. I had planned to take just the plane captain, Koffel, and Chief Photo Mate Hicks back to Philadelphia direct from the ship. However, Lieutenant Jim Daniels, the SEU catapult officer, talked me into letting him ride over the bottom hatch below the cockpit with Koffel. Chief Hicks sat in the cannoneer seat to my right.
"When the catapult fired, the yoke flew out of my hands as the pilot's seat slid back into the bulkhead, doubling up the steel jury straps that were only designed to keep the seat from moving forward. Some observer on the ship had apparently tried to adjust the pilot seat position and the latch had never re-positioned in its track slot. There we were, airborne off the bow with no one near the controls. But thank God for Jim Daniels! Jim had played tackle for the Georgia Tech Rose Bowl team immortalized by "Wrong Way" Right. With one shove of his mighty arm that seat went back along the tracks into position where I could grab the yoke and reach the wheels-up lever. We then departed for NAS Norfolk, landing an hour later none the worse for our experience."
Syd Bottomley left SEU in June 1945 and naval career attaining the rank of Captain. In the course of his wartime service he was awarded the Navy Cross, the Distinguished Flying Cross with Gold Star, six Air Medals, and the Presidential Unit Citation. His campaign awards include: American Defense Service Medal, Fleet Clasp; American Campaign Medal; and the World War II Victory Medal.

Philly, huh? Lived there, actually Langhorne, for a year in the early 80's. Used to go out to the Willow Grove NAS to watch the P-3s come in and go out. Always reminded me of growing up at various NAS around the country. Game just ended. I was disappointed.
