Convective breakthrough'' after an {ital inclined} {ital planar} {ital light} {ital fluid} {ital layer} is struck by a shock wave is observed and quantified. The results of direct numerical simulations are interpreted and a convective breakthrough time {ital t}{sub {ital b}} is quantified. Initially, vorticity of opposite sign is deposited on each interface of the layer. Breakthrough occurs when these vortex regions approach and bind'' into a dipolar vortex (or jet head) that moves away from the wall. Variations of {ital t}{sub {ital b}} with Mach number of the incoming shock waves are given.
