The Rutan Model 202 Boomerang is an asymmetrical aircraft built by Burt Rutan in 1996. If there is a single engine failure, it would not become dangerously difficult to control due to asymmetric thrust. (2500×1044)

It's pretty, but not a new idea

My husband has a picture of that plane (not that particular one, though) in his office.

That's weird. Symmetry is beauty, but the side pod and main fuselage are strangely round and attractive.
