I believe you're right about that.
But why on earth would there have been a radar in that immediate area? Radar range was extremely limited at that time -- and a plane flying at 375m would have been invisible to any radar that was over the horizon.
No way is there a radar installation around Howland Island. Nor was there any radar that could've seen her from Hawaii.
This author doesn't know what he's talking about.
I did enjoy the Norwich City bit, though.
