I've seen a larger version of the same photo before! Unfortunately, I can't remember the site where I saw it. It's definitely a photo manipulation using a computer. These days, you can make some some incredible digital manipulations, if you're skilled enough.
The FAA certainly wouldn't allow this to happen! The Golden Gate Bridge is a large suspension bridge, so the air vortices generated by the DC-10 would've rocked the bridge big time like the Big One that Californians hope will never happen in their lives. People and cars would be knocked around and probably even fall nito the Bay. That is even if the DC-10 was going at a speed near the point of stalling, which I don't really know, but it must be at least 375 km/h (233 mph)! The DC-10 is a big and very heavy aircraft, that's why it can't fly as slowly as a smaller a/c like a Beechcraft 1900 or a Dash 8. Not to mention that the tail'd be ripped right off by getting caught on the bridge if the crew flew the plane too high above the water. That would be a serious and fiery accident, as the fuel tanks get torn apart and ignite. It's also a very serious hazard to shipping and smaller recreational boats if the plane was flying that low whether it was under the bridge or not.
Remember the film footage and pictures of the Tacoma Narrows Bridge in Washington State getting really whipped by high winds until it got ripped apart? This is one of the best known footage ever made of a bridge being damaged. And that's a pretty good idea of what''ll happen to the Golden gate, if the DC-10's tail got caught in the bridge, although it may not get really ripped apart by the wake vortices generated by the plane.
