The Aero series is unique for its ammunition type, Aero Gliders, which glided through the air father than a standard missile would fly.
The Aero series was a rather short-lived series, as it began and ended within two years. It only had one blaster, which was a re-release of the 1992Original NerfNB-1 Missile Blaster, as well as one product.
Interestingly, the series was involved with NASA (National Aeronautics and Space Administration) in order to create a glider toy that would fly extremely far. This experiment took place in 1997, and the Gliders product was launched with two variations after months of research.
