1. A wind turbine blade with a leading edge and a trailing edge, said blade comprising: an upper shell member and a lower shell member, each of the upper shell member and said lower shell member comprising a chord-wise forward edge and a rearward edge, the forward edges bonded at the leading edge and the rearward edges bonded at the trailing edge with a bond paste applied between the respective forward edges and rearward edges; at least one of the shell members comprising a first inspection window defined therein along one of the leading edge or trailing edge at a location corresponding at least to a design minimum bond width of the bond paste applied at the respective leading edge or trailing edge; the first inspection window providing a visible access through the shell member such that a visible indication is generated through the first inspection window when bond paste is injected and reaches the minimum bond width location or beyond in the chord-wise direction; and the first inspection window comprises a passage defined through core material of the shell member, the passage filled with a translucent material, wherein the core material of the shell member prevents visible access through the shell member such that the visible indication of the bond paste is given only when the pond paste flows under the first inspection window.
