Airwolf

During the dogfight between Airwolfs I & II, the Sunburst defensive flare system was used offensively to blind Harland Jenkins. This was the only time this was done during all three of the Jan Michael Vincent Seasons. Note: It would seem that the Flash Blindness Prevention system was not incorporated into the Airwolf II helmet design. The system is designed to protect a pilot's eyesight when there is is a sudden intense burst of light. Hawke has such a system built into his helmet as demonstrated in the Season 1 episode To Snare A Wolf.

Before Jenkins shot at the security guards, you could hear him taunt them, but you could not see him mouth moving through the helmet. He was just smiling.

Although it was never addressed until now, and Archangel seemed pretty shady and illusive throughout his interaction with String and Dom throughout the series, they all refer to each other as "friends" in this episode.
