What type of aircraft produce the single contrail? Fighter aircraft or something else? One can easily tell if it's a 747/A340 from the 4-contrail pattern or the 2/3 engine aircraft from their respective contrail patterns. I can only figure that the single contrail patterns are from some military jets. Thoughts?

Sometimes, depending on the weather, the separate contrails may seem to merge, and appear as one contrail. Either that or some military single engine plane.
