They indicate a massive transverse expansion and rather short lifetime of the system. The quantitative analysis in framework of the blast-wave model yields, however, unphysical results and suggests that the model may not be applicable in description of two-particle correlations. I then discuss generalisations of the blast-wave model to non-central collisions and the question how spatial asymmetry can be disentangled from flow asymmetry in measurements of v_2 and azimuthally sensitive HBT radii.proceedings of 18 NPD conference of the EPS "Phase transitions in strongly interacting matter", Prague, August 23-29, 2004, 10 pages, 5 figures, to be published in Nuclear Physics ANuclear TheoryCollective dynamics of the fireballtext
