Remember when an untimely security exercise on the Potomac River on Sept. 11, 2009, nearly crippled the Washington region with visions of terrorism running through the minds of local officials?
Well, here's fair warning of another training assignment going on Saturday on the Potomac that could cause a similar panic for the public (and CNN) without a head's up.
Rescue boats will practice pulling people from the water as part of a simulated airplane crash that will test Ronald Reagan National Airport emergency personnel's response.
The Metropolitan Washington Airports Authority said smoke and fire may be visible from the south area of the airport, and river rescue boats and helicopters will also be in the area.
The exercise will run from approximately 9-11 a.m.
Alert your friends and neighbors before the region shuts down for no reason for a second year in a row.
