The clue = C/N 61-751
I was heavily involved in many tortuous S61 SAR mod programmes over the years, at Redhill, but I can't remember whether BDIJ was a primary 4-axis, dual hoist SAR machine or one of the back ups.
Another 61 of the four that arrived wasn't a Bristow machine but an ex British Airways aircraft G-ASNL. Fifty years old, ditched in the North Sea, 30 years ago, due to G-box failure, sank while being recovered and still going strong. All four 61s have just come out of Iraq!!!
Only rumours of where there off to next.................
