Md. police resume rescue service after crash

WASHINGTON - September 30, 2008 - State Police spokesman Greg Shipley said in a news release that only one helicopter had resumed operations. It made a test flight Tuesday evening and can respond to calls depending on the weather.

Shipley said other helicopters will resume service after ground and in-flight checks of glide scope equipment on each one have been completed.

Federal investigators were documenting the accident site Tuesday at the suburban Washington, D.C., park where the helicopter crashed early Sunday.

National Transportation Safety Board spokesman Keith Holloway says a preliminary report may be released next week.
