Airplane! watch as "Otto" takes control of the plane, inflates a female companion, and takes off. Jerry Zucker, Jim Abrahams, and David Zucker (collectively known as Zucker, Abrahams and Zucker, or ZAZ), wrote "Airplane!" while they were performing with the Kentucky Fried Theatre, a small theatre they had founded in 1971. To obtain material for comedy routines, they routinely recorded late night television and reviewed the tapes later primarily to pull the commercials, a process Abrahams compared to "seining for fish". During one such taping process, they unintentionally recorded the 1957 film "Zero Hour!", and while scanning the commercials, found that
Time-triggered architecture aerospace and related systems. Use of TT systems was popularised by the publication of "Patterns for Time-Triggered Embedded Systems" (PTTES) in 2001 and the related introductory book "Embedded C" in 2002. The PTTES book also introduced the concepts of time-triggered hybrid schedulers (an architecture for time-triggered systems that require task pre-emption) and shared-clock schedulers (an architecture for distributed time-triggered systems involving multiple, synchronised, nodes). Since publication of PTTES, extensive research work on TT systems has been carried out. Time-triggered systems are now commonly associated with international safety standards such as IEC 61508 (industrial systems), ISO 26262 (automotive systems), IEC 62304
