Not the first time this has happened. I remember seeing pics of an F15 in Germany (IIRC) that landed with the right wing outboard of the engine nacelle gone. This was at least 5 years ago.
McD can probably program a simulator to demonstrate the flight characteristics of a one winged Eagle.
MD said that it wasn’t possible to fly an F15 with one wing missing.
They have. Further, the ability to change flight control laws to adapt to changes in aircraft configuration was investigated back in 1993 or so, based on this event.
