Under active runway, 1 meter deep, intentionally? That would be the most moronic "safety measure" I can imagine.

  Looking at the article, this was a WWII air base converted to a civilian airport. The bomb was not paved over due to laziness; no one knew the bomb was there. Hindsight being 20/20, maybe they (the Japanese) could have used metal detectors when they were updating the runway? But, given that they didn't find this, I suspect it wasn't practical back then. Perhaps now there will be an effort to use modern technology to find these?

    A bomb like this could be pretty deep though. They're pretty aerodynamic and heavy yet compact. They'd go through mud pretty easily. If it's a few metres deep I doubt it would show up on a metal detector. This is why so many are still found.

      There's now ground penetrating radar that archeologists use to find chambers deep in pyramids. I doubt it was around when the runway was built, but now there's clearly a case to use it.
