It seems a Russian S-300 long-range anti-aircraft missile had a slight . . . er . . . problem on launch the other day. Its tube fired it right out, but the main rocket motor failed to ignite. That's when it showed the real problem with a vertical-launch system . . . namely, that what goes up must come down. Watch in full-screen mode for best results.
I hope there weren't any operators in the launch vehicle at the time!
This also illustrates the difference between 'cold' and 'hot' launch methods. The Russian technique is to 'blow' the missile out of its vertical launch tube by means of an auxiliary system, usually compressed air. The missile's motor fires only after ejection. This is known as a 'cold launch' system. It has the advantage that, if the main rocket motor fails to fire, it can eject the missile anyway; but if the missile tube is pointed straight up, you get the result seen above. The USA uses a 'hot launch' system, where the missile's own motor fires inside the tube and shoots it out. If the motor fails, the missile doesn't launch at all. This forces a labor- and time-intensive extraction procedure afterwards, but at least the missile can't fall back on its launcher!
