My mind might be confusing me (again), but didn't Lockheed Martin withdraw engineering/certification support in the last year or so ? I also seem to recall that there were only 2 SIMS left, one being the RAF one and the other in Miami (?). Whatever, it's nice to see these older types getting another go before becoming scrap even if their economics isn't quite that expected of most operators these wafer thin margin days.
