Materials found by hikers not data from '85 Bolivian air crash - U.S.

WASHINGTON (Reuters) - The U.S. National Transportation Safety Board (NTSB) said on Tuesday that materials found by two American hikers in Bolivia do not contain any data from missing data recorders from a plane that crashed in 1985 killing 29 people.

Two U.S. hikers recovered several metal fragments in May, one damaged spool of magnetic tape and two additional off-spool sections of magnetic tape from Eastern Airlines Flight 980, NTSB said.
