I think i would rather NVG became a night requirement, that may change though if ADS-B and WAAS delivers as promised. The infrastructure right now only really suits the airlines. The aircraft in question i think was an IFR ship, should we be more focused on NVG, it doesn't help in inadvertant IMC but wouldn't it make a bigger safety improvement for the buck.
I read that AM said NVG are in short supply because of the war and would have used them if they were readily available.
