Mark gets a no-prize that'll collect the occasional jackrabbit for bringing us this spectacular footage of low-flying military aircraft. I couldn't quite make out the type, I think it may be some sort of late 70s Mirage (F-1?). Couldn't see any markings either, but the terrain (combined with the type) makes me think it perhaps might be Israeli.
The barrel rolls at low altitude may not simply be showing off. If my simulator experience is any indication, when flying low and fast it's actually easier to keep the altitude low by inverting and pulling "up", then rolling upright.
