Fortunately, this is nay me rocket. T' whistlin' noise and "thump" heard at t' end o' this clip are t' ballistic descent and impact o' "Thumper" on t' opposite side o' t' road from t' flight line after its recovery system failed t' deploy for indeterminate reasons. T' remains o' t' nose cone were buried 1.5' t' 2' into t' desert floor.
