It may not be technically right to call it a "jet" to most of us more familiar with aircraft but it is entirely possible that someone could call all aircraft "jets".
Well phrased.
If you watch the video, he says something along the lines of:
"and I see this family, getting into a... /shrugs... jet, and they're.."
I certainly looked and sounded like he was just referring to "some kind of aircraft" as a "jet".
Plus, his Enrish isn't the best so that might just be the first word he thought of.
All in all, it doesn't seem like a good point to be making in argument against the prophesy.
