I may have taken a glass too many, but I felt I needed just a fraction more coherence to the story. And maybe a bit more decision making about what its aims were. Special effects were pretty good. More so if you consider it had a (comparatively) low budget. Suitably daft, e.g. falling out of plane, landing on exploding fighter, being blown back through bomb bay. But "good ideas" were uncritically included and a stronger hand was needed in the editing suite.
