NEW YORK (AP) — Robust demand for commercial jets and an increased pace of production helped Boeing earn $1.36 billion in the third quarter, up 18 percent from the same period last year. Adjusted for non-operating costs, earnings came to $2.14 per share, better than the average estimate of $1.95 per share from analysts surveyed by Zacks Investment Research. In the past quarter alone, Boeing booked 501 net plane orders, bringing its backlog up to more than 5,500 airplanes valued at a record $430 billion. The vast majority of that increase comes from its popular 737 — a single-aisle plane that is the workhorse of airlines around the globe — and the 787 Dreamliner, a lightweight fuel-saving aircraft that had numerous delays and hiccups.
