Nice little rumour or two doing the rounds at the moment.
Seems to be they are trying to force the treasury's hand wrt RJ at maingate by destroying any chance of extending the life on the R1s.
When the first plane shortly goes out of service it will be cut up and the fuselage only, sans wings, sold off to a local air museum inside 3 months of arrival.
Second airframe sold off to a different museum a few months later, but that would at least have a set of wings attached.
So any defence review or change of government that says, for example, "why are we bothering buying this? We could just extend the R1". Would get the reply "What R1s?".
