Hmmm, I've never given that any consideraton -- which was probably exactly what the writers intended for us all. Ooops
Unless there's a special military licensing program, then for any occasions when we have seen T behind the wheel (nothing comes to mind immediately :blush
, we have to imagine what the DMV would make of giving a state driving license to an imposing Jaffa warior with a raised gold tattoo on his brow. I don't think they take official license photos of drivers wearing hats designed to obscure a significant portion of the face.
As for JQ, no problem getting him a license, but they haven't addressed any aspect of his training or study of Earth and the USAF. We are left to suppose that after months on the base and in the time since being picked for SG1, there's been intensive training and inculturation programs for JQ.
Of course, we never saw what programs were offered to T nor what training DJ received after his return from Abydos. Presumably, the military trained both in weapons use, tactics, regulations and procedures even though they are civilians. DJ made have had some of training (though it was never addressed in the film) before the inital mission to Abydos.
In
Waterworld the entire team had to parachute to the Russian base. S & J would have done such jumps before, but we're left with impression that neither D nor T had parachute training -- unlikely if they are part of a USAF secret program and had gone through some equivalent of boot camp.
We are left with conflicting assumptions and that is a fault in the writing. Some assumptions are safe to make, based on what has been presented and what has been left unsaid, but may be infered from the situation, plus a basic knowledge of what is possible and what is required.
But the faithful are always ready to produce rationalizations for plotholes and continuity errors. I don't think that the audience should be doing the writers' job for them. When a question like previous training programs comes up we should find something in the past eps that accounts for it or at least does not contradict it.
If trained by the military to drive and to shoot, why not also be trained to parachute?
