		Ship's Computer Misread Exocet, Magazine Reports

	  LONDON (AP)--The British destroyer Sheffield, sunk by an Exocet
	missile in the Falkland Islands war, had its computer programmed
	against Soviet missiles and identified the French-made Exocet that
	hit it as friendly, the weekly British magazine New Scientist
	said Friday.
	  It said that after the attack, "all computers aboard the rest
	of the task force in the South Atlantic were reprogrammed to
	correct the error.
	  A Defense Ministry spokesman did not deny the magazine's story
	but called it "inaccurate.  No panic changes were made to the
	software in Royal Navy ships as a result of the Sheffield
	incident.  Type 42 ships (destroyers) have the ability to
	distinguish between various missiles," he said.

   Or, in the words of the immortal Eccles:
	"Don't worry--dat mine, it can't hurt us--it's one of ours."

   A question for all you Motorola fans out there: can you sync a chip
with an EXORset?

   Seriously, I like Asimov's approach to selling weapons abroad: install
a hidden, remote-controlled cutoff switch to deactivate anything being
used for inappropriate purposes.  I think it was Anacreon that tried to
attack Terminus with a ship that Salvor Hardin had had specially
equipped for the occasion...
