In a turboprop, popping it back into beta and hearing the engines make cool turboprop sounds
In a jet, cruising at 380 and having a 747 pass 1000' above while an A330 flies 1000' below at the same time, both spewing contrails and giving a real sense of speed.
Flying around thunderstorms at night.
Fighting a 35-knot gusty crosswind into JFK on the VOR 13L, seeing the A320 in front go around because of wind shear and greasing the landing.
Waking up next to the hottest flight attendant in your crew
Going through a snowstorm at night. Looks like warp speed in Star Wars
St. Elmos fire
That feeling when you finish a 4-day trip and have 6 days off
Nailing the flight with a fed in the jumpseat
Phew got a little carried away, guess I just love what I do. Call me "Captain Happy"
