The flared muzzle is the defining feature of the blunderbuss, differentiating it from large caliber carbines; the distinction between the blunderbuss and the musketoon is less distinct, as musketoons were also used to fire shot, and some had flared barrels.
Wernher von Braun's space station concept (1952) Although Germans, Americans and Soviets experimented with small liquid-fuel rockets before World War II, launching satellites and humans into space required the development of larger ballistic missiles such as Wernher von Braun's Aggregat-4 (A-4), which became known as the Vergeltungswaffe 2 (V-2) developed by Nazi Germany to bomb the Allies in ...

If the near-light-speed space craft is interacting with matter that is moving slowly in the planetary reference frame, this will cause drag which will bleed off a portion of the engine's acceleration. A second big issue facing ships using constant acceleration for interstellar travel is colliding with matter and radiation while en route.
These were assembled in pairs by the manufacturer and then shipped to Kennedy Space Center by rail for final assembly. [13] The segments were fixed together using circumferential tang, clevis, and clevis pin fastening, and sealed with O-rings (originally two, changed to three after the Challenger Disaster in 1986) and heat-resistant putty.
