Letter: Letters: Blow out

Published 8 February 1992

From CHRISTOPHER LAMBTON

I am writing this on board an Intercity 225 Scottish Pullman, currently
due to arrive one hour and 20 minutes late at London King’s Cross. The delay
has been caused by stone-throwing vandals who broke the outer layer of a
double-glazed window. Speed has been reduced because ‘pressure from a passing
train could cause the window to blow out, or in’ the ‘Senior Conductor’
explained.

Which? Would the weakened window blow out, or in?
