MRI Safety at 3T versus 1.5T Jennifer Jerrolds R.T.(R)(CT)(MR) Shane Keene MBA, RRT-NPS, CPFT, RPSGT Citation: Jennifer Jerrolds & Shane Keene: MRI Safety at 3T versus 1.5T: The Internet Journal of World Health and Societal Politics. 2009; Volume 6, Number 1. Abstract
Autonomous Flight Systems Inc., is the R&D arm of the project, supported by notable consulting firms in the aircraft field. All fabrication is done by its sister company Zero Time Aircraft Corporation, and several key subcontractors.
The Shuttle uses a rocket propulsion system to get into orbit, but during re-entry the aircraft is actually an un-powered glider. Small steering rockets are used for maneuvering early in the re-entry because the low density of the air at altitudes above 50 miles makes aerodynamic surfaces ineffective.
