aerial survey i
Until the middle of August, a • U.S. Geological Survey single en- ! gine research plan will be conducting I low-level airborne surveys in parts | of Virginia and Maryland near; Washington, D.C. |
The aircraft will be flying over • Rappahannock, Culpeper, Fauquier! and Loudoun counties in Virginia! and Montgomery County in! Maryland. |
William F. Hanna, a supervisory J geophysicist at the USGS National; Center in Reston, said the purpose! of their airborne surveys is to collect! geophysical data for the agency’s! National Geologic Mapping Pro-J gram. !
Scientists from the USGS, in co | operation with other federal, state; and local agencies will use the data i to better understand the compose; tion and structure of the Earth’s! subsurface in the five counties. :

Scientific in- J strument pods extend from the; plane’s wing tips, he added, and the! pilot and crew are specially equipped j and trained for low'-level flight. !
