So, BAe management was building the RJX as a five year stopgap? Hmm, that's not the view of many people who were in the offices or on the shop floor at Chadderton and Woodford. They were being sold on the aircraft having at least as long a life as the 146 and, given the amount of revised and new engineering in the project, five years would not have been a realistic time for payback.
You might be right of course as the same totally ridiculous thinking is evident in the stated BAe view in November 2001 that the regional jet market had died in the flames of the WTC.
The real truth will one day come out that BAe just didn't and still don't want to be in the aircraft manufacturing business.
