Summary: Static firing tests with large (solid fuel ?) rocket motors.
Description: A large rocket unit, supported vertically (and pointing upwards) on a test rig, is fired. The unit cannot be seen in any detail. The same test firing is then shown in close-up. This sequence is then repeated twice. Another large unit which appears to contain 12 solid fuel rocket elements is seen (again with the rockets pointing vertically upwards) with a parachute suspended over it. The unit is fired, blasting the parachute away. There are close-ups of the unit with its spent rockets.
