The first of a three phase project, this metal building located at the Springfield Airpark is an airplane hangar specially designed for Lear jets. The hangar can house 8 to 10 planes at a time and has a useful mezzanine for observation and storage. With all three phases complete, the entire Spectra Jet complex will have two identical hangars, separated by a long central building that serves as administrative offices and terminates in an observation area allowing visitors to see planes descending or taking off.
