A modified CL-60 Challenger aircraft flies a low-level approach past an instrument landing system being used in 2007 in Southwest Asia. The 853rd Electronic Systems Group staff will soon be releasing a request for proposals for a deployable instrument landing system, which will be leaner and more transportable.
