The variety of Earth-based and space-borne instruments used to investigate comet Halley created an unusual opportunity to compare direct and remote methods of studying cometary matter. The central theme of many investigations was to clarify the role of H2O in the nucleus. Incontrovertible evidence for neutral H2O as an abundant volatile species in any comet is contained in near-infrared airborne spectra of comet Halley. These airborne spectra are summarized for comparison with previous infrared studies of comets and with other investigations of comet Halley. These airborne measurements establish new criteria for evaluating the spectroscopic sensitivities of future studies of comets with remote infrared methods.
