Progress Spacecraft Launch Successful

The failure to have one safe launch *does* mean that a launch vehicle is unsafe, so there's that.

Pretty much any launch vehicle is unsafe, by definition. You're sitting on top of (literally) tons of highly flammable fuel, along with similarly large amounts of liquid oxygen. There is nothing about this that is "safe" by conventional standards. Even after you've safely survived the combustion of all that fuel, you are then in one of the most hostile environments known to man. Elevated radiation levels, lack of gravity causing your bones and muscles to waste away, and a hard vacuum on the other side of a rather thin piece of aluminum and/or glass. In short, human spaceflight is inherently dangerous, yet we still do it, and quite rightly so.

Of the existing launch vehicles, the Soyuz design is the single most successful and reliable launcher ever designed and operated. Since 1973, there have been 745 launches of the Soyuz-U design with 724 successful launches (with most of the failures in the early days). The soviets, and subsequently the russians, have made continuous improvements and refinements to the design of this rocket, leading to the closest thing we have to a routine launch system. As one astronaut I've worked with said, "You can take a Soyuz, pick it up in the middle with a crane, shake it, then stick it on the pad and launch it in the middle of a blizzard, and it will still make it to orbit."

Given the choice of Shuttle, Soyuz, Falcon 9, or some other launch system, I would always take the Soyuz.
