> (IIRC, with the overall records, the compassion is more even.) You can consider ill-fated Komarov's flight as a part of early testing of Soyuz. Sort of like Apollo-1 crew forced making Apollo much more fire resistant. Soyuz, as a non-reuseable technology (actually, some parts are reused) benefits from incremental improvements; Soyuz of today has quite different equipment than it had in late 60-s. Komarov, as well as Volkov, Dobrovolskii and Patsaev paid with their lives to make Soyuz safer... this is part of the reason this old design still carries two to four flight per year without casualties. Still way less safer than the aspired gold standard of commercial aviation :) - relatively recently Soyuz had some ballistic aerobraking scenarios, where safety margins are thin...
