fact the airline is virtually brand-new. here's abc's david car lay. >> with 194 people on board, it was a wide body airbus a-330 like this one that suddenly lost power to both engines. it was cruising more than three hours into its flight from singapore to shanghai at 39,000 in bad weather when the engines shut down. no power. the jet would lose 13,000 feet in altitude before pilots were able to get both the engines working. >> when you've got a highly computerized airplane, maybe this was a glitch in the software. whatever it was, on a new airplane, it's highly unusual. >> singapore airlines tells us the first engine restarted almost immediately, procedures call for the pilots to descend, keeping speed up and then turn the engine's start switch to try and reignite the engine. it worked. the jet landed safely and mechanics found nothing unusual on the weeks old jetliner. >> this happened over the weekend.
