Explosions Rattle NW Area

Dozens of startled Washington residents called police and fire departments last night after loud and unexpected bangs and booms filled the air.

The racket appeared to be part of what was billed as a stunning fireworks display, put on for the opening of a festival at the Kennedy Center.

The festival, appropriately enough, celebrates the arts of China, the country credited with the discovery of gunpowder and fireworks.

The display, according to the Kennedy Center Web site, was created for the opening of the festival and was dubbed an "explosion event." It was to include such seldom-seen displays as flying dragons and a pyrotechnic tornado. Those who did not get to see it apparently heard it.

Train Injures Metro Worker

A Metro employee was hit by a train and left unconscious about 4 p.m. yesterday as he worked on tracks between the Braddock Road and King Street stations, said Metro spokeswoman Lisa Farbstein.

The worker, whom Farbstein did not identify, was taken to a hospital with head injuries.

Fairfax Plans Park in McLean

Fairfax County officials have announced plans to spend $16.1 million for an easement on a 41-acre historic property in McLean and create a public park. It would be the largest single land expenditure in the county's history.

The property is part of the Salona estate, owned by Daniel H. DuVal and Clive DuVal III, sons of the late state senator Clive DuVal II (D-Fairfax). The DuVals have agreed in principle to allow the county Board of Supervisors and the county Park Authority to acquire a conservation easement on the land, protecting it from development and allowing the county to use it indefinitely. If the DuVals sell the land, the county would have first right of refusal.

Officials said the open space will include athletic fields, a playground and a picnic area.

Motorbike Crash Kills Teenager

A 17-year-old from the District was killed Friday night in Chillum when his motorbike crashed into a sport-utility vehicle, police said.

Marcus Moore of the 100 block of Tuckerman Street NE was riding a Baja Motorsport dirt runner south on Chillum Road when it crashed into a Ford Expedition that was turning left into a parking lot on 18th Avenue, said Cpl. Kim Brown, a police spokeswoman.

"People say we're changing the integrity of the neighborhood, but I think it needed some change. There's a lot of sloppiness in the neighborhood."
