General Pelletier talked a bit about that question.
Part of the ongoing assessment is on what the threat is—what it is made of and what does it emit? The missile we're talking about here is an infrared missile, so is the object hot enough? Is there a chance that we're going to have a shot at that? That assessment happens as the object moves across.
We thought the CF-18, on that object, would have been able to attempt it. It was going to be the first attempt from a CF-18. Before taking that shot, there were a few tests that would have let us see if we had a good shot on it, but it did have an armed missile to take that object down.
