Air America (1998)

Rio and his buddy Wiley are supposedly just ordinary pilots working for the Latin American air transport company Air America. In truth, they are undercover secret agents receiving their orders directly from the State Department in Washington. As part of their duties they investigate international crime, protect witnesses, rescue people who need rescuing, and occasionally get themselves out of messes that their boss, Furman, keeps getting them into as he tries to line his own pockets.

Fear of Flying (Season 1, Episode 13)

Wiley has a panic attack while in flight. Afterwards he gets grounded and must undergo a psychiatric evaluation. There is much more to the incident, as Wiley suspects he has been victimized by a scandal involving mind-altering drugs.
