Boeing Company

The flight, which took off from Kennedy International Airport on Friday, safely returned to the airport, where crews saw that the slide was missing, according to the airline.

The plane had taken off from Kennedy International Airport when crew members noticed problems near its right wing, Delta said. What became of the slide is unknown.

The airline expects fewer deliveries of Boeing planes than before, and cited “significant challenges” in achieving growth plans because of it.

The manufacturer has had to slow production of its popular 737 Max planes after a hole blew open on a jet during an Alaska Airlines flight in January.

The plane maker, which is searching for a new chief executive, is likely to consider a small number of people, including several former Boeing executives.

Merle Meyers, who left Boeing last year after a 30-year career, said he was speaking publicly about his experience because he loved the company “fiercely.”

Una auditoría de la Administración Federal de Aviación descubrió que Spirit AeroSystems, empresa proveedora de Boeing, usaba jabón Dawn y una tarjeta llave de hotel en el proceso de fabricación. La empresa dice que sus técnicas son ingeniosas, no descuidadas.

Sam Salehpour, an engineer at Boeing for over a decade, testified that the company introduced production shortcuts in an attempt to address bottlenecks.

After a Boeing engineer went public with safety concerns, the company invited reporters to its South Carolina factory and top engineers vouched for the plane.

An F.A.A. audit found Spirit AeroSystems using Dawn soap and a hotel key card in the manufacturing process. The company says its techniques were inventive, not careless.
