Iraq Dr. Fox To ask the Secretary of State for Defence which units have remained in Iraq longer than their planned deployment because of shortages of air transport in the last 12 months; how long each has remained in Iraq; and if he will make a statement. Des Browne No units have remained in Iraq longer than their planned deployment because of shortages of air transport in the last 12 months. Scheduled routine flights may however be delayed for a variety of reasons, including adverse weather, technical difficulties, ground handling problems, de-conflicting aircraft movements and force protection of airfields.
