"Altair has also taken biomimicry into the aerospace sector. In one example the company worked with Airbus to remove about 1100 pounds from the A380's rib–wing package, a weight reduction of nearly 40 percent." - Popular Mechanics
Altair rotates rapidly, with a velocity at the equator of approximately 286 km/s. [nb 2]  This is a significant fraction of the star's estimated breakup speed of 400 km/s.  A study with the Palomar Testbed Interferometer revealed that Altair is not spherical, but is flattened at the poles due to its high rate of rotation.  Other interferometric studies with multiple telescopes, operating in the infrared , have imaged and confirmed this phenomenon.
