Today's clip is a 4min slideshow of the SAAF Pilatus PC-7 MK2 photographed in Durban, Virginia. Pretty cool soundtrack too, sang by the band Nickelback, "If today was your last day."

These aircrafts are undergoing an upgraded under the Avionics Replacement Programme where the first 2 were complete two weeks ago on July 14th. Dean Wingrin covers the story on his website here.
