David Morgan, BA Cert Ed., co-authored the Take-Off students book. He has spent most of his teaching career in Further Education and Industry, teaching general English, EFL and ESP. He has completed numerous specialist projects, such as teaching short courses to air traffic control personnel and producing a 200-hour intermediate ESP course for a leading Middle Eastern electricity supply company. Until 2003, he was in charge of the English Language programme at the on-site training centre of a major oil company in Libya, where national employees from all technical fields followed courses in General English and subject-specific ESP. During this time, he pioneered the establishment of the UCLES examinations in order to produce an externally validated objective yardstick by which courses and teaching could be judged. He has retired from full-time teaching but is still interested in working on materials writing and editing projects which involve producing reading and listening passages based on specific subject areas. Nicholas Regan is an ELT writer and teacher trainer. Since 2002, he has worked as an independent consultant for teacher development in the primary and secondary sectors, covering teaching in under-resourced and crowded classrooms, and working with Ministries of Education, Universities and schools in China, Africa, the Middle East, Latin America and the EU. He has also been involved in the evaluation of state provision of English teaching. For several years he taught English at secondary school level in Latin America. For Garnet Education, he has co-authored the ESP course Take-Off, and has also contributed to ESAP: Mechanical Engineering, Progressive Skills in English, New Skills in English, UAE English Skills series and the English for Libya series. He has also written materials for ELT training at Diploma level. His other work includes examining and assessment design for ESOL teaching qualifications; pre- and in-service training; and supervision of dissertations for MA TESOL students at the University of Birmingham. He holds the Trinity College London LTCL DipTESOL and an MA in Applied Linguistics from the University of Reading, UK.
