One of the projects this summer was to develop a GPS logger that could be dropped out of a plane onto a glacier, the idea being that by watching how the co-ordinates change we can see how the glacier shifts. To assist in the development of the instrument, several dry runs were conducted over Rothera. Two Twin Otters flew in tandom, one to drop the logger, the other to film the decent. On Christmas Eve the end of one of these dry runs coincided with the return of the Dash 7. It is not often that all three planes are in air over Rothera at the same time so Alan (head pilot) made the decision to take full advantage and conduct a fabulous fly by over base.
