A training exercise involving several military aircraft will take place early Tuesday over the D.C. region, authorities said.

The North American Aerospace Defense Command and its Continental U.S. NORAD Region will be conducting the exercise, called Falcon Virgo 18-03. It will include an F-16 fighter, a C-21 transport plane and an MH-65 Dolphin helicopter, which will fly over the D.C. region from about midnight until 2:30 a.m. Tuesday, officials said.

In the event of bad weather, the drill will be moved to Wednesday morning. Continued bad weather will postpone the exercise or it will be canceled, officials said.

The exercise involves training flights, officials said, with the cooperation of the Federal Aviation Administration, the Joint Air Defense Operations Center and the Office of National Capital Region Coordination.

Officials said the exercises are "carefully planned and closely controlled," with the goal of ensuring that officials have a "rapid response capability." Such exercises have been conducted since the Sept. 11, 2001, terrorist attacks, officials said.
