Twas nothing, to indicate that the IAF didn't know who it was, is a diplomatic way of saying "we know you're there, gotcha, but we ain't gonna total ya". There is full radar coverage of all of Isreali airspace, plus the Egytian, Syrian, Lebanese, Jordanian, Cypriot & some Turkish, & I would guess a way bit further. No probs, just a bit of finger trouble inputting the CFP co-ords into the box
