It's an interesting one to say the least. One of the principals of OO development is that you shouldn't return an object out of a constructor that requires further configuration to be useful*. In other words, you shouldn't need to set additional properties before the class is useful. In this particular case, the fact that you can get to the Launch code without setting it, and the first point that you notice that there's a failure is at this point would indicate that the Booster should have been applied earlier on.

*Now, looking at your sample, it would seem that what you are looking at here is an object that would typically be composed using Dependency Injection, so it would be reasonable to assume that the DI code would actually compose your object for you. This would mean that you would be exposing a dependency that your code was reliant on - and this is where it gets slightly murkier. If you favour the wide constructor approach to composition, then every time you need to add an extra dependency to your class, you have to add it to your constructor, and add a backing field for that type. You may prefer the dependency property (I'm not using this in the WPF way here) approach, which means that you would expose a property for it - and this could be an auto property so you wouldn't need to add the field yourself as the compiler takes care of this for you behind the scenes.
