Do you know the jokes in civil aviation?

In 1970s, in view of more and more bird strikes endangering the safety of aircraft, Boeing asked NASA engineers to design a special gun, which could hit chickens on the cockpit glass of aircraft as shells to simulate bird strikes during high-speed flight, so as to test the safety design of the cockpit.

When Airbus engineers learned about it, they asked to borrow a gun to test the windshield of their new plane.

After paying high rental and transportation fees, the test system was quickly transported to Airbus headquarters in France.

On the day of the test, the chicken was launched and smashed on the windshield of Airbus at a high speed of about 200KM/H, and the engineers were scared to death.

Because the chicken not only penetrated the windshield, but also interrupted the driver's seat, and finally passed through the cockpit door, the whole chicken was nailed to the bulkhead. Airbus engineers with weak legs quickly revised the design and re-demonstrated.

But after a few months, there is still no result, every time.

Finally, Airbus reluctantly told Boeing the terrible test results, and attached Airbus's unique and detailed windshield design scheme, humbly hoping that Boeing could provide some technical suggestions.

After Airbus sent a complete design and experimental video to Boeing engineers, it didn't get a reply for a long time.

Airbus had to pay a huge consulting fee again for this.

Boeing responded quickly, but the content was only one line:

Thaw the chicken first.
