Rockwell B-1A Lancer
The Rockwell B-1 Lancer is a supersonic variable-sweep wing, heavy bomber used by the United States Air Force. It is commonly called the "Bone" (from "B-One"). It is one of three strategic bombers serving in the U.S. Air Force fleet along with the B-2 Spirit and the B-52 Stratofortress . The B-1 was first envisioned in the 1960s as a platform that would combine the Mach 2 speed of the B-58 Hustler with the range and payload of the B-52, and was meant to ultimately replace both bombers. After a long series of studies, Rockwell International (now part of Boeing) won the design contest for what emerged as the B-1A. This version had a top speed of Mach number, Mach 2.2 at high altitude and the ability to fly for long distances at Mach 0.85 at very low altitudes. The combination of the high cost of the aircraft, the introduction of the AGM-86 ALCM, AGM-86 cruise missile that flew the same basic speed and distance, and early work on the B-2 stealth bomber reduced the need for the B-1 ...

GSR Class B1a
The Great Southern Railways Class 800 steam locomotives were built principally for express passenger work on the Dublin to Cork main line of that company. These locomotives were designed under the supervision of E. C. Bredin with his Chief Draughtsman, H. J. A. Beaumont, preparing the drawings. They were the largest and most powerful engines ever to run in Ireland by quite a large margin, and the only three express passenger locomotives to be built in an independent Ireland. Design The engines had three cylinders and boiler pressure. The nominal tractive effort was , which corresponded with Great British main-line power. Further, it was the only design which exploited the full extent of the extra width afforded by the gauge. Originally four or five were to be built, named ''Maeḋḃ'', ''Maċa'', ''Táilte'', ''Gráinne'', and ''Deirdre'', but only three were eventually produced - 800 ''Maeḋḃ'' in 1939, with ''Maċa'' (801) and ''Táilte'' (802) in 1940, along with a ...
