US Air Force STAFF Sergeant Paul Fung of the 305th Aircraft Generation Squadron operates the AirPlus, a new de-icing system developed by the Air Force Research Laboratory. The AirPlus produces a high-velocity air-jet by drawing ambient air into a compressor. The air then exits the compressor at 13 pounds per square inch and heated to 100 degrees Fahrenheit. Once the air reaches the nozzle, it returns to its ambient temperature and pressure, a process of converting thermal energy into kinetic energy. Some of the advantages are the use of air rather than glycol as the major de-icing medium. The air is diffused slowly from the nozzle for increased coverage and the minimal use of glycol ...

B-1 Lancer is a supersonic variable-sweep wing, heavy bomber built by Rockwell and used by the United States Air Force. It is commonly called the "Bone" (from "B-One"). It is one of three strategic bombers in the U.S. Air Force fleet as of 2018, the other two being 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 with the range and payload of the B-52. 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 2.2 at high altitude and the capability of flying for long distances at Mach 0.85 at very low altitudes. The introduction of cruise missiles and early work on the stealth bombers led to the program being canceled in 1977. The program was restarted in 1981, largely as an interim measure due to delays in the B-2 stealth bomber program, with the B-2 eventually reaching initial operational capability in 1997. This led to a redesign as the B-1B, which differed from the B-1A by having a lower top speed at a high altitude of Mach 1.25, but improved low-altitude performance of Mach 0.96. The electronics were also extensively improved during the redesign, and the airframe was improved to allow takeoff with the maximum possible fuel and weapons load. The B-1B began deliveries in 1986 and formally entered service with Strategic Air Command (SAC) as a nuclear bomber in that same year. By 1988, all 100 aircraft had been delivered. Originally designed for nuclear capabilities, the B-1 switched to an exclusively conventional combat role in the mid-1990s.
