Heroines

Republicans close to the White House whisper about the prospect of an alliance between Ms. Haley and Vice President Mike Pence, possibly to run as a ticket in 2020.

Aides to both scoff at such suggestions, but the slightest hint of such a pairing would be likely to enrage Mr. Trump, who has made it clear that he plans to run for re-election. The talk was exacerbated in recent days when Mr. Pence named Jon Lerner, Ms. Haley’s deputy, as his new national security adviser, while allowing him to keep his job at the United Nations.

That plan collapsed within 48 hours when Mr. Trump grew angry at reports that Mr. Lerner had made anti-Trump ads for the Club for Growth, an economic conservative advocacy group, during Republican primaries in 2016. Mr. Lerner stepped down from the job in Mr. Pence’s office.

For any pilot in this situation the most difficult and urgent thing to judge is how responsive the airplane is to their commands. An airplane as crippled as this one becomes difficult to handle. With only one engine working and damage to the other causing unusual air drag, the pilot must correct for asymmetrical power and drag—the airplane naturally tends to swing away from its direct course.

Here it is striking to compare Captain Shults’ plight with that of Captain Chesley “Sully” Sullenberger in his legendary “miracle on the Hudson” landing. Sullenberger lost both engines to a bird strike, but his airplane, the Airbus A320, had “fly-by-wire” controls that gave him an automatic safety margin by restricting the control movements to a computer-dictated “envelope.” In contrast, the flight controls of the Southwest 737, although monitored through computers, remain as they were in the analog age, with the pilot controlling directly through a “yoke.”

And this is where Captain Shults’ background came into play. She is an ex-Navy pilot and one of the first women to fly the “Top Gun” F-18 Hornet, eventually becoming an instructor. Landing supersonic jets on the decks of aircraft carriers is one of the most demanding skills in military aviation. Now, flying on the one engine called for her to use all of her “seat of the pants” instincts to nurse the jet to the runway.

Normally a 737 on final approach would deploy its wing flaps to their full extent, to reduce landing speed to around 140 mph. But Captain Shults’ skills and experience forewarned her that an airplane flying that slowly with its flaps fully extended and with asymmetrical power could become fatally unstable in the final stage of the landing, so she used a minimal flap setting to maintain a higher speed and stability—taking the risk that the landing gear and particularly the tires could survive a higher speed impact.

As the jet came into land the controllers in the Philadelphia tower, looking at it through binoculars, could see that there was an open gash in the side of the cabin. At the same time it was reported that a large piece of the left engine’s cowling had fallen to the ground 60 miles northwest of the airport.

Captain Shults faced another problem with the speed of the landing: she could not deploy the airplane’s engine thrust reversers to help brake the speed after touchdown because of the damage to her left engine. However the touchdown was perfect and, once slowed, the jet came to rest on a taxiway where a fire crew sprayed the damaged engine with foam and put out a small fire from leaking fuel.
