Having in the distant past hung around for days at the Ft Bill LS while the engineers fixed a problem (and eventually having literally called the AA to get the one last 24volt start to complete the engine change), I concur that almost anything is cheaper than a Chinook lift 500 miles from the nearest Chinook base. In these resource-limited times one only gets Chinooked off if there is no other way out (witness the effort it took to fly out of the Cairngorms four or five winters back).

Still willing to return to service if you've run out of has-beens.
