As pilots, co-pilots here....why are so few go arounds being executed...in your opinion?
Quite possibly because it's a maneuver rarely practiced on the line or in the simulator. A light jet aircraft can be a handful for someone that's not well trained or rusty.
Then I think every pilot is suffering, to some degree, from the press-on-itis "want to get the job done" syndrome.
Fatigue certainly doesn't help in the decision making process either.
