We had some pretty mixed weather during the course of RIAT this year. There was plenty of sun but also some rain. Even when it was dry, the humidity levels were pretty high and this meant that anyone wanting to get some vapour shots was going to have plenty of options. For the turboprop powered aircraft, when they were putting on the power, it meant that their props were pulling tip vortices. Here is a selection of shots of different planes extracting water from the air during their take offs.
