To try and create a standard, i consider a widebody to be full width of the headbox.(as listed below)
Other widebodies such as gottlieb etc are technically a 'mid-body' or 'half-widebody', yet still wider than 'normal body'
Sadly everyone still refers to the mid-bodies as widebodies.
So, is a full widebody now mega-wide or something?
