Boeing's 737-10 backlog can turn into cash only if deliveries ramp. Its largest, highest-seat-economics MAX variant has 1,555 firm orders, about 30% of the MAX book, and rivals the A321neo; airlines pay most on delivery. A complete MAX family could retain carriers through shared training and parts. The muted stock reaction is a discount window for patient delivery bulls only if they can sit through production-rate, quality and airline-induction delays; certification brings no immediate cash. x.com
