The Air Force effort to upgrade 112 C-5 airlifters has passed a major hurdle—the successful test of new General Electric engines mounted on one of the airlifters as part of the C-5 Reliability Enhancement and Re-engining Program. There was some concern that the technical risk on this massive overhaul effort would be too great, but everything worked—start up, electronics, thrust reversal, and run up to full power.
