As Boeing's 797 Nears, GE `Wrestling' With What to Do on Engines

General Electric Co. said it remains unconvinced that demand for Boeing Co.’s potential midrange aircraft, nicknamed the 797, will be enough to justify developing a new engine for the jet. The U.S. turbine maker needs to do more work on the proposals, especially since Boeing has yet to decide whether to recruit an exclusive engine provider or involve two competing suppliers, GE Aviation chief David Joyce said Monday at the Farnborough air show. “We’re still wrestling with what the size of the market is,” Joyce said in a media briefing.
