The plane is on the KillaThrill site - with both wings.
Acrobatic planes don't carry fuel in the wings. They're like 914's, weight is in the center.
And if an R/C plane can do it, a real acro plane can do it.
But it has happened before, so it is possible.
Israeli jet F15 fighter lost an entire wing, flew back and landed on afterburner. Needed the extra power to fly. I'll try to find the link. It's true.
Here's the link:
That DID actually happen, absolutely.
