A time lapsed exposure of a night-time departure illustrates this edition of the Journal, a summary of the major developments in international civil aviation last year as well as airline traffic and financial forecasts for the 2005-07 period.

Included in this year's report is a commentary on the challenge of reporting and interpreting air transport statistics, which may be more of a science than most people appreciate (page 20).
