Description: The Keystone XB-1B was the designation assigned to the Huff-Daland XB-1 after the original Packard 2A-1530 engines were replaced with Curtiss V-1570-5 Conqueror engines (Huff-Daland was reorganized (More) The Keystone XB-1B was the designation assigned to the Huff-Daland XB-1 after the original Packard 2A-1530 engines were replaced with Curtiss V-1570-5 Conqueror engines (Huff-Daland was reorganized and renamed Keystone in 1927 -- between the time the XB-1 was built and the XB-1B was modified). The XB-1A designation was skipped because it was already assigned to the Dayton-Wright XB-1A "Bristol Fighter." The improved -B aircraft had better performance than the original, but still didn't compare favorably to other aircraft of the period and never entered production. The performance of the Curtiss XB-2; for example, was significantly better than the XB-1B, but the Curtiss aircraft was initially rejected also; in part because it was too big to fit into existing hangars.

Two flights were made and both takeoffs were beautiful, both landings superb. All morning, mechanics had hovered about the big ship while Walter E., Lees, representative of the Packard Motor Company, went over the two engines. The clouds were whisked across the heavens by a brisk northerly wind, and by noon the sun was covering the field and a small knot of interested spectators had appeared. Lieutenant Frank B. Tyndall, of McCook Field, Dayton, O., special Government representative at the aircraft factory, slipped on his parachute a little before 2 o'clock, fastened his helmet and climbed into the pilot's seat. A mechanic turned the crank of the inertia starter and the port motor roared. In a few seconds, the starboard motor was keeping it company. As the blocks were pulled away from the wheels and the great ship's eighty-five feet of fuselage swung around, the photographers scattered downfield for pictures. The Super Cyclops rode easily; its tail lifted expectantly as it moved toward the eastern end of the green. Last week, of course, it had taxied as nicely as this. But this was to be the test. Lieutenant Tyndall gave it the gun., the ship came toward the newsmen and, far short of the mark where they had looked for it to leave the ground, it sailed from the earth. The distance was less than 100 yards from its starting point. Every one was amazed at the ease with which five tons of steel and fabric had mounted toward the skies. For twenty minutes then it flew. Once its pilot throttled down the engines and the ship's nose came down slightly, and a few of the uninitiated on the ground held their breaths. Lieutenant Tyndall was testing for minimum speed at that time. Round and round it flew, banking like a lazy buzzard, mounting higher and higher until it was hardly bigger than a pursuit ship. And then it came down, slowly, slowly, going in big circles and finally skimming a barn roof and landing perfectly. There was an interval of an hour and a half and then it rose again. The Super Cyclops is made to carry 2700 pounds of explosives and six Lewis machine guns. It will carry a crew of five or six and its explosives carrying capacity can be raised to 4000 pounds. There are two water-cooled Packard engines, twelve-cylindered, of 560 horsepower each. The wings measure fifty-five feet. After it has been given five or six hours in the air here, it will probably be sent by rail or flown to McCook Field. (Less)
