From Air Power guy:

This, sadly, was all too common a prank during the Vietnam conflict. It happened to our neighbor, whose F-105 pilot husband was shot down over North Vietnam.
People need to understand how this works…
This kind of notification is done in person, by a uniformed officer, who may be accompanied by a chaplain, nurse or both. Fortunately, the low casualty rate makes this more feasible (I almost used the word “easier” but that certainly isn’t the right choice). Most of us have been on call for that duty in our careers (and you always are if you’re a commander and you can be there yourself).
Whoever did that underscores the depths to which too many in this country will stoop to get even when decisions are made and things happen in America that they disagree with. It is repugnant, but it happens and will probably happen again, sad to say. I firmly believe there’s a special place in Hell for people like that.
