Some years ago an airliner landed here in Richmond after having been shot by
someone on the ground. It was a completely coincidental thing where someone
shot into the sky and just happened to hit an airliner. The news report
showed the bullet hole; other than that the plane was fine.

May or may not be relevant, depending on the following
two questions:

1. Did the bullet penetrate into any pressurized part
of the aircraft ?
2. What height (and speed) was it flying at when it was hit ?
