.... The fisherman pulls once, twice, then three times on the line. The hook fragments and part of the hook careens like a rocket back toward the fisherman. With no time for the fisherman to react, the metal fragment pierces his left eye and embeds in his skull. During examination at the hospital, the doctors...

... in the V1 and V2 rocket programme. The steel had a fine grain structure, high ageing resistance and low impurity levels resulting in significant low temperature toughness, further enhanced by a double heat treatment procedure. Further details of the steel are given elsewhere ( 3 ). The fitness for purpose...

.... Note that these do not require the contents to be flammable; steam/water and other nonflammable systems can also result in BLEVEs. Due to the time for the contents to flash to vapor, these events tend to have long durations, on the order of 100 to 1000 ms. Fragment throw and rocketing of vessel pieces...
