The McKinley Climatic Laboratory is both an active laboratory and a historic site located in Building 440 on Eglin Air Force Base, Florida. The laboratory is part of the 96th Test Wing. In addition to Air Force testing, it can be used by other US government agencies and private industry. [2]
The HEAT-H2 Test Unit is an arc-heated aerothermal tunnel providing high-enthalpy flow at high Mach numbers and dynamic pressures simulating hypersonic flight at pressure altitudes up to 120 atm. H2 utilitzes an N-4 Huels-type arc heater to generate high-temperature, high-pressure air for expansion through a hypersonic nozzle into the evacuated test cell.
The site today consists of various buildings, a bunker, two fire control towers, a recreation hall, four 3-bedroom cottages, eleven 2-bedroom chalets, two townhouses, four efficiency units, eleven RV sites, a pavilion and spaces for tent camping. It is now operated by Hanscom Air Force Base as a military recreation area. The site is open only ...

Local fire departments responded to an estimated average of 44,210 home structure fires caused by heating equipment, including space heaters, each year from 2016 to 2020, per the NFPA.
Aerodynamic heating is the heating of a solid body produced by its high-speed passage through air. In science and engineering, an understanding of aerodynamic heating is necessary for predicting the behaviour of meteoroids which enter the Earth's atmosphere, to ensure spacecraft safely survive atmospheric reentry, and for the design of high-speed aircraft and missiles.
New York City law regulates the safety of space heaters. Space heaters for sale in the city must have a thermostat to control temperature, an automatic shut-off feature if the heater tips over or overheats, and must be certified and labeled by a nationally approved organization or laboratory. [15]
