NASA has enlisted the help of several former staff members from the SR-71A Blackbird program to assist in the secret restart of the supersonic jet, which was canceled in 1998. The SR-71A is a high-speed reconnaissance plane designed by Lockheed Skunk Works and was used by the US military for over 30 years. The former staff members will provide expertise on the plane's design and technology, including its unique airframe and propulsion systems. The restart of the SR-71A project is part of NASA's efforts to develop a new supersonic aircraft that can fly faster than Mach 5, or five times the speed of sound. The new aircraft is expected to be used for both military and civilian purposes, including reconnaissance, surveillance, and transportation. The project is currently in its early stages, and NASA has not released any details on the timeline or budget for the project.
