AB: The fastest coronal mass ejection observed to date by the LASCO coronagrph onboard SOHO was also the best observed thanks to the Max Millenium co-ordinated observation campaign running at the time. Data from RHESSI, TRACE and SOHO from April 21 2002 are presented which yield a clear timeline of the physical processes involved and their relationships to each other. The causality of the solar flare-CME system is discussed and implications for theory and modelling are presented. Other large flare/very fast CME events are analysed and agreement with the paradigm is studied. Particular attention is paid to the acceleration of such very fast CMEs and the nature, magnitude and timing of the acceleration process is characterised within the limits of the observations.
