You asserted that the 139 could not do a particular rescue when it could. I was correcting you.
Your profile doesn't mention what SAR job you do so I understand your lack of knowledge of how SAR works.
Like the Wessex was not expected to do the Seaking role the 139 is not expected to do the same role as the S92. As RJS said it would be nice to have an all large SAR helicopter fleet but big is not always better. There were some jobs that were more suited to the more agile Wessex than the Seaking, such as picking a child out of an inflatable "play boat", or getting close to a cliff sticker whose hold was precarious and the Seaking downwash would have been too much.
