Endurance Ship's Antarctic Sinking
Ship not designed for compressive pack ice; Shackleton knew its weaknesses.
Structural issues: weaker deck beams, long machine compartment, no diagonal bracing.
Early wooden ships endured 1.7-2.7 times more compressional load.
All 28 crew survived, findings published in Polar Record.
Study says ice tore keel, not rudder.
