Crash of Iberia Flight 610

Date: February 19, 1985 • Location: Berriz, Spain

A Boeing 727 operating as Iberia Flight 610 crashes Mount Oiz in Spain, killing 148; it is the deadliest accident to occur in Iberia's history and the deadliest to occur in Basque County.

The Boeing 727 is an American narrow-body trijet that was developed and produced by Boeing Commercial Airplanes. After the heavier 707 quadjet was introduced in 1958, Boeing addressed the demand for shorter flight lengths from smaller airports. On December 5, 1960, the 727 was launched with 40 orders each from United Airlines and Eastern Air Lines. The first 727-100 rolled out on November 27, 1962, first flew on February 9, 1963, and entered service with Eastern on February 1, 1964.
