@coach joe Thanks for the view of your F-6 model. What a plane, after introduction in 1943 the Navy ruled the sky's over the Pacific. It had a 13:1 kill ration against the zero and along with the Marine usage a 19:1 overall kill ratio in the war years. It was nicknamed the "American Ace Maker" . 75% of all Navy aircraft victories are credited to the F-6 and 56% of all Navy & Marine Corps victories (Marines often flew the F-4U Corsair). @MELGAR and @jhz563 - Wow interesting heritage fellows. I worked in Engineering for Naval Air Systems Command (Melgar you might know this as "BuAir") and visited Grumman many times especially on the A-6 and F-14. Even though I was an Aero Engineer, my work involved those "strapped down" pieces that Coach Joe saw as I was deeply involved in structural fatigue damage assessment based on operational use of the aircraft. Navy pilots loved Grumman aircraft, not because their performance was always the best (although it was good) but because they were TOUGH! You had to have a tough airframe to withstand the rigors of carrier launch and arrestment. Of course that toughness carried over into combat and helped their aircraft protect the pilot and crew. We used to call the Beth Paige Grumman facility the "Grumman Iron Works"! But all joking aside they built great aircraft.
Well back to railroads
