It is indeed a long time since I was a hands on radar engineer but the physics hasn't changed since then, only the equipment has got smaller and lighter.
How do you know the island was not visible on radar? Much more likely that they could see it. Perhaps thought the route they were flying was some sort of safe low level route.
