While doing some para training near Bloemfontein a certain DC3 crew used to do the odd shoot up of the packing and gathering area we used near the airfield. On one occasion the came in between two military ten man tents and as well as flattening tents and occupants with their wash they upset a couple of packers who had canopies laid out for packing. After that there was always one packer keeping a weather eye out for the Dak and if they could hear it but not see it they got pretty antsy and lay down on the partially packed 'chutes.
Unfortunately the Dak was damaged on the last day of the course when the beast nosed over while doing engine run ups. It left two gouges in the runway and had to be carted away on a low bed trailer and we finished up jumping an assortment of helos and converters. (For a definition of converters see the thread regarding flying a Kudu on the African Aviation forum.)
