Your task is to reconstruct this crossword. One of each of the 26 letters of the alphabet have been removed from the crossword and needs to be put back in. In addition, the black squares need to be added in.

The final pattern of black squares is symmetrical in the horizontal axis and in the vertical axis, but NOT along the diagonal axes. There is at least one black square in every row and every column, and all words are at least three letters long. Every word in the final solution contains both given (black) letters and alphabet (red) letters.
