Many pilots fail to realize that a go-around scare probably half of the pax on the plane ****less. They don't know what's going on and assume the worst, near miss etc.
I've seen go-arounds covered in the media far more sensationalist than in Mr. Kenny's piece. The article illustrates the need for some kind of public education with regards to go-arounds. Maybe it should be included in an FAQ in the inflight magazine... In any case, always make a PA as soon as possible after a go-around, explaining what happened and why, and stressing that it is a controlled operation and not out of the ordinary. Don't tell them you practice it two times a year in the sim, they don't find two timeas a year reassuring. Just don't let them leave the plane thinking they experienced a near miss...
