Hey air pig! What does "Kegworth was the same.." mean?
What does "sears at the time.." mean?
What does "bled out into their legs" mean? Do you mean internal hemorrhaging?
Kegworth: that investigation in the deaths, helped to make changes into design as the report from Manchester also did for operations, cabin design etc.
Sears: should read seats, will edit this point
Bled out is when you lose your blood volume into a place it is not meant to be either internally or all over the floor when your ulcer or oesophageal varices pop, but drop 2lts of blood from each fracture leaves you with very little blood to go round, resulting in death. Blood does as you assert does not have to be visible when you loose the vast majority of circulatory volume.
