Empty Flight Theory at Boeing

Boeing presents as a service to the community the following information on Forces of Flight/Lift/Basics:

• Lift is the upward force that counteracts gravity and enables airplanes to fly.
• Lift keeps birds, gliders, and airplanes aloft as they move forward through the air. Lift is also generated by the spinning blades of a helicopter.
• Aerodynamic lift is based on Daniel Bernoulli’s Principle, which states that the pressure of a flowing fluid or gas decreases as its velocity increases. To take advantage of this, an airplane wing, like a bird wing, is designed with a distinctive shape called an airfoil. This shape creates the greatest possible lift for the airplane.
• The shape of an airplane wing, the angle at which the wing meets the airflow, and the speed of the airplane all affect the lift.

This information is preceded by a friendly: 

• Welcome to "Forces of Flight," a new Boeing program created to help classroom teachers to excite and engage students about science.
• We hope that you will find this program helpful and interesting. 
• We are proud to partner with teachers who are making the effort to inspire the next generation of scientists.
• In addition to being informative, this program is intended to promote student inquiry by linking the information on the posters and web site to a series of classic hands-on physics experiments that demonstrate how the forces of flight actually work.

But what Boeing offers to young minds eager to understand why it is possible to fly, is not a correct explanation of the generation of lift, in fact no explanation at all: It is only a vague hint that somehow it is the shape of a wing that generates lift, which is directly contradicted by suggesting that it is maybe instead the angle of attack that gives (a symmetric wing) lift. 

None of the natural questions from the students can be answered this way which can only teach that science is a hopeless mess which cannot excite and engage students. 

The question then presents itself: Does Boeing know how a wing generates lift?

To check out I sent today the following mail to Boeing:

• On the web site The Secret of Flight I present a New Theory of Flight (submitted to AIAA) giving a new explanation of the generation of lift and drag of a wing, which is fundamentally different from classical text-book theory.
• My question: How does Boeing explain the generation of lift of a wing? 

I will report the answer. Here it is:

You can find a great deal of information using the search tool. Try clicking on the “About Us” link, which will take you to pages on history and research assistance (including an aviation reading list and related aerospace sites).

Due to the high volume of requests we receive, we cannot provide any additional information or research assistance than what can be found on our public website.

Thank you for your interest in Boeing.

Kind regards,
