A U.S. B-52 bomber carried a stealth cruise missile on a four-hour flight across remote northern Canada in the first test of the advanced weapon outside the United States. "As far as we know, everything proceeded smoothly," said Maj. Jan Martinsen, Canadian spokeswoman. The missile remained attached to the bomber in the test designed to monitor guidance systems. The B-52 flew from the Beaufort Sea in the Arctic to a Canadian forces base at Cold Lake in northern Alberta. In Toronto, eight members of the Toronto Disarmament Network staged a sit-in protest at the offices of the Progressive Conservative Party.
