No, but I have flown the 139 in the SAR role which is, I suspect, far more than you have done DM.
As ever DM, AW's promises will have the devil in the detail and, even by your statement, they are only planning to assemble the SAR variant in Yeovil - just how many jobs will that actually create/save and for how long if the expected number is 200?
It is smoke and mirrors in order to get SARH to act as a product launch (unproven product) for the 189.
