The purported advantages of the blended wing body approach are efficient high-lift wings and a wide airfoil-shaped body.

It had a fairly high-lift, low-speed wing with a very low wing loading.

It had a sleek body with a single-step hull and a slender high-lift wing with fixed floats.

Aircraft with high-lift wings and vectored-thrust engines to produce extremely short take-offs and landings.

For instance, the P-38 Lightning with its thick high-lift wing had a particular problem in high-speed dives that led to a nose-down condition.

It had a thick, high-lift wing for fast climb characteristics and for holding a large fuel supply.

The XCO5 needed a high-lift wing suitable for high-altitude work.

The high-lift wing has pronounced dihedral on the outer span.

While it successfully demonstrated the performance of the new high-lift wings, the Fairey Hamble Baby was placed in production instead.
