You ask how chinese lanterns can hold formation like that, and before I had seen them doing such things, I would have asked the same question... but I
did witness such an event, and then went and had a look at how and why they appear to travel in such a way. First, when lanterns are released, they
are often released in groups, usualy fairly close to eachother. When they ascend they get caught up in thermals and air currents. Now air currents
are often very wide, so the main bulk of a group, can be taken in the same direction, and at the same speed. Since they move at the speed of the
airflow, they appear to be moving deliberately in unison. However, this is merely an interesting visual representation of the movement of air, rather
than a genuine excersize in aerobatics.
