Okay. I'll start, and then I'll pass it over to General Prévost.
The first unknown for us during the actual intercept phase of the objects was, again, characterization. Where is the object coming from? For the objects, we could not discern or didn't have a visual on any form of registration on the objects. Normally, even an air balloon or a commercial or civilian aircraft would have a registration to actually demonstrate the country of origin.
Obviously, as I pointed out, the rate of closure of the fighters made identification of those registration marks very difficult. This was combined with low light conditions for two out of the three object intercepts. Also, the capability of the payloads that may have been carried by the objects is an element of high interest, in order to actually assess not only surveillance capability and collection capability but potential threat capability as well.
General Prévost, do you want to add something?
