We present the latest data of the c-axis bicrystal twist Josephson junctions experiments of Li et al. and of the artificial and recent natural cross-whisker junction experiments on Bi 2 Sr 2 CaCu 2 O 8+δ ( Bi 2212) of Takano et al. and Latyshev et al., respectively. These combined experiments provide strong evidence for a dominant s-wave order parameter and for strongly incoherent c-axis quasiparticle tunneling in Bi 2212 for T≤Tc.
