Bob that must have been FSB 5, the mortars used to time the slicks......The only way to get to that pad was haul-ass low level and when you got to the mountain haul back on the cyclic, and do a cyclic climb and plop down on the pad and kick the shit off and didi mau, and dive down the mountain on take-off, and watch the mortar round hit the sandbag pad yikes!
