Oh Creaser, let's not allow the facts to distort your argument! You're wrong on lens, noise, distances and height. A number of times on both Friday and Sat PIXX was letting a twin come underneath. You cannot compare the 83dB of PIXX with the much louder twin - come on!
And what the rescue co-ordinator said was - "if that's yours..." to a BBC reporter. He was pointing at a twin.
See you in the pub.
