I am only a pilot not some high flying City boy, but let's do some simple maths. Supposed you would get 2.2 for your 3 year old airframe (I know that is stretching it a bit but let's give them the benefit of the doubt), so you lost 600-800k on that airframe and lets suppose you could get a replacement for 2.7 (again let's give them the benefit of the doubt) so that would cost you an additional 500k for your replacement. So all in all the exercise, not even taking the fact that Sterling has dropped severely, would cost you 1.1 - 1.3 mill. So having flown, let's again give them the benefit of the doubt, 600 hours on said airframe since you guys purchased it, your little replacement exercise for a "new" model would have cost you in the region of 2.000 USD per hour. Again let me stress I am just a humble pilot, but those numbers don't make a lot of sense to me.
