After weeks of anticipation, locations for two key stops that will round out the 2017 Red Bull Air Race calendar have been announced; and while both are in Europe, they’ll test the skills of the World Championship pilots in distinctly different ways. On 2-3 September, the raceplanes will take off at the classic Air Racing destination of Porto, Portugal for the first time since 2009. Then, just two weeks later on 16-17 September, it’s a return to the motorsport hub of Germany’s Lausitzring.
