A large part of the team is dedicated to the construction of the HB-SIB, our second solar aircraft, and is commuting between Payerne and Dubendorf. HB-SIB will be larger than the HB-SIA and the cabin comfortable enough for a flight of several days.

Meanwhile, in Payerne, we have kicked off another round of test flights which will run until the end of October. This test phase will give Bertrand Piccard further opportunity to familiarise himself with the prototype and to notch up the training hours needed for future missions. Markus Scherdel, our test pilot, should also be taking the controls to test settings at high altitude.
