DCist photographer Meaghan Gay captured these images of today’s special effects explosion on the Potomac River, near the Key Bridge. The pyrotechnic effect went off around 3 p.m., and lasted just a few seconds. The Washington Post also has video of the effect, which was filmed for a television pilot being produced by CBS, titled Washington Field. Whether that pilot will ever see the light of day, of course, remains to be seen. The Post’s video shows that the remaining smoldering flames were safely put out.
