I think I'm right in saying that a TV program that is downloaded on YouTube suggested that BAe's 146 needed to sell circa 240 units to break even? I think on that basis the 146 would have been viewed as a sales success and I wondered if there was a view or data on other UK aircraft - civil or military would make a good comparison.
Back in the 80s I knew one of the Hatfield sales team. He said that the more airframes they sold, the more money the company lost - they were going for below cost, as alluded to in a previous post.
