It sounds like planes humping or some kind of aeronautical anomaly.

Last week, Bob told me that on his way home from work he saw two planes sitting on top of each other down at the airport. The following day, LANL sent out a lab-wide email indicating that there had been an accident at the airport and that all flight operations were suspended until an investigation had been performed. I went down there today and took some pictures.

The fact that the planes were tied together and that there were roller cards under the tail of the lower plane and the right wing tip of the upper plane suggests that they were rolled away from the accident site, most likely to clear the runway. As I was leaving, I ran into my friend Dan (who I have been flying with before) and he said that the two planes had landed at the same time, one on top of the other. He was there when they extracted the pilots, who both survived.

So I guess somehow both planes got onto final without seeing each other or communicating on the radio. Sounds like someone wasn't flying the pattern... Yowzer.
