During tests, an American Stealth Bomber does its job all too well and it disappears. Secret agent John Glames is sent to a fictional country in South America to find it.

You might not believe it if you haven't lived through that period yourself, but screen savers were a profitable commercial market for a long time.

Remember those old coin-ops where you sat in a cage that rocked with you as you raced a car? The first one I came across and was immediately fascinated with was called Outrun. You were racing a Ferrari Testarrossa through cities, along beaches and over mountains.
