Yes. It was indeed a pair of wood pigeons, Harold and Clarence. Rumour is that they had just been for a couple of pints of John Smiths in town and were heading back home. Apparently they tried to sneak across the runway without clearance. It is not known if either of them had their transponders turned on. What makes it worse is that Harold was on the phone to his wife at the time. Apparently his last words were “this will make the buggers late!!!”
They were both married with several chicks to support. RIP!
