ZK323 / DN (cn 322/BS084) An 11(F) Squadron Typhoon pulls up hard into the vertical over RAF Coningsby during the Enthusiasts Event. Note the smooth laminar airflow over the wing, and the turbulent sections induced at the edge of the leading edge slat, shown well by the vapour. [EOS 7D and Sigma 120-300 F/2.8 OS]
