To my eye it did appear that on the empty hook run the irb was trying to formate on the helicopter and failing. Good enough reason to switch to an alternate procedure.
Quite why the winchman was yoyo'd in and out of the irb only the crew on the day will know.
I am sure the punters at Cleethorpes enjoyed it. Apparently there is not SAR demo at the Harwich Sea Festival because, according to the press, "the Wattisham Aircraft has been bought by a private company"
