Figure 1. HIPO's flight electronics rack. Computers and monitors for controlling the instrument and acquiring data have been mounted in accordance with approved airworthiness requirements. The monitors and keyboard can be stowed in the rack for takeoff and landing. Each science instrument will have its own airworthy rack-mounted electronics.

Figure 2. Spectrum of NGC 7027 taken by FLITECAM in grism mode on the Lick 3-meter telecope in July. A total exposure time of 90s was used and the resolving power is ~2,000. Strong emission lines are identified, including the broad PAH feature at 3.3 um. Many absorption features due to terrestrial water vapor are superimposed on the intrinsic spectrum of the source which will not be seen in similar spectra observed from SOFIA.

Figure 3. FORCAST (red cylinder) mounted on the 200-inch Palomar telescope in late June 2005. Foreoptics convert the f/16 Palomar beam to the f/20 FORCAST/SOFIA beam, and image the fixed Palomar secondary onto a chopping mirror for ground-based observations. The FORCAST on-board electronics box can be seen on the right hand side of the instrument.
