IATA expects five billion passengers and $1 trillion in airline revenue in 2025     

Aerotime

All these efforts will help to mitigate several drags on profitability that are outside of airlines control, namely persistent supply chain challenges, infrastructure deficiencies, onerous regulation, and a rising tax burden. In 2025, industry revenues will exceed $1 trillion for the first time.

From albatrosses to slimy eels: Aircraft design and concepts inspired by nature 

Aerotime

Winglets and Sharklets Both Airbus and Boeing operate aircraft with wingtip devices that are designed to increase aircraft efficiency by removing drag. The devices would prove to “reduce wingtip drag” and increase “fuel efficiency by 6-7%” but would need be positioned uniquely for each aircraft type.

Today in Aviation History: 58th Anniversary of ‘Pardo’s Push’

Vintage Aviation News

Air Force photo/Senior Airman Ridge Shan) Pardo attempted to push Amans Phantom by contacting its drag chute compartment, but turbulence made this impossible. During the Vietnam War, Pardo saved the lives of a fellow Phantom aircrew when he used his own aircraft to push their battle-damaged jet almost 90 miles into friendly airspace.
