On the CVR it has the co-pilot reporting a contact at 11 o'clock, 6 miles at 32secs or about 0.75 n.m. before impact. Drumacappel wasn't at six miles then; it started at about 5 miles. What was at six miles was the highest point of the island on the eastern side. A radar tilted at 0 degrees would have seen the coast, one titled up wouldn't.
