I thought a "tailskid" was the actual piece of the plane designed to skid along...like on a spad. every plane (well, jet) I've flown has a tail skid or bumper for just the situation of dragging on the tail.
if you have ever seen the great movie, "Thirty Seconds Over Tokyo", early on in the training, the tail bumper or skid on the B25 flown by Ted Lawson drags along the ground...its there for a reason...they later named the plane "the ruptured duck" for this maneuver.
hope you get to see the film...except for the mushy parts a real fine aviation movie.
tangently yours!
