We understand from the passage that the reason why the USAF is giving so much importance to the “wing warping” technique is ----.

Aviation is about to go back to its roots. Nearly 100
years after the Wright brothers' first heavier-than-air
powered flight, the US Air Force is testing an
experimental plane that uses “wing warping”, which
is the steering and control technique that kept
Orville Wright aloft in 1903. But this time round, it
will be at supersonic speeds. Unlike conventional
aircraft wings, which use movable surfaces like flaps
on the wings and the tail, wing warping bends the
entire wing. The USAF call it “active aeroelastic
wing” technology, and is investing $41 million in the
project in the hope that it will lead to lighter, more
manoeuvrable supersonic planes.
