The Rebellion of pro-Khomeini air force Technicians

On 9 February, a rebellion of pro-Khomeini air force technicians broke out at the Doshan Tappeh Air Base. A unit of the pro-Shah Immortal Guards attempted to apprehend the rebels, and an armed battle broke out. Soon large crowds took to the streets, building barricades and supporting the rebels, while Islamic-Marxist guerillas with their weapons joined in support.
