As reported by the RAF's Inspector of Flight Safety in 1992, we "benefitted" from the fact the Argentineans had better and more up to date technical pubs for their aircraft. So much so, that when the "captured" Chinook pubs were compared with the crap we had, henceforth the RAF used the Argentinean ones, despite theirs being a different model of Chinook. One assumes they'll seek a rebate for this.
