Kinematically complete experiments have been performed on the three-body exit channels in 7.5 MeV/amu /sup 238/U+/sup 238/U and /sup 238/U+/sup 248/Cm. No evidence was found for an instantaneous three-body breakup. Instead, a two-step nature with minimum scission-to-scission times of 10/sup -20/ s has been derived even for intermediate nuclei Z>110. However, the observed fission fragment angular distributions in this region are incompatible with the usual saddle-point concept.
