Why did Col Halt not see the flashing light sooner?
This is an intriguing question for which the Orford Ness lighthouse offers a natural answer. Recall that Col. Halt’s men had called him to the scene with the words ‘The UFO is back’, meaning that they had already seen something out there. But, as we hear from Col Halt’s tape recording, no one pointed out the flashing light to him until he had spent some time at the site. Where had it got to? Had it gone away and come back again, or was it there all the time but hidden?
In my view, the second answer is correct. The Orford Ness lighthouse is directly visible from only a limited area along the forest edge, so anyone just outside this range would not see it – even a few yards makes all the difference.
On this scenario, the landing site that Halt investigated was probably just to the north of the area from which the lighthouse is visible. Only by moving a few paces to the south would the flashing light on Orford Ness be brought into direct view.
Why Col Halt’s men did not immediately show him the flashing light which they had originally called him out to see is an intriguing question which only they can answer.
