While many advances have been made in aviation, one thing remains beyond human control: the weather. While weather satellites and advanced forecasting techniques have improved weather prediction, airplanes still need to travel in all kinds of weather. Once airborne, airplanes can often avoid severe weather, but they still need to take off and land in all weather conditions including the worst that winter has to offer. By spraying a cloud of cold-water mist onto a model, NASA Glenn Research Center's Icing Research Tunnel (IRT) simulates ice formation on aircraft surfaces during flight. The tunnel has been making it safe to fly in icing conditions since the early 1940s. Work continues today in the investigation of the physics of the icing process to support the development of aircraft icing computer codes. Additionally, the IRT is used for the development and certification of ice protection systems for commercial and military aircraft.

Please note the following important guidelines:
- Advanced registration guarantees admission to the tour that begins at the Briefing Center.
- Access to the Saturday tour program is limited to U.S. citizens and Lawful Permanent Residents (LPRs).
- All adult visitors are required to present government-issued photo identification, and LPRs are required to present their Permanent Resident Card. This includes bus drivers for scheduled groups.
- NASA reserves the right to limit the use of cameras and cell phones during the tour.
