25 Dec 98:

Reviewed draft CAD drawings and noted several discrepancies in the dimensions vs the original drawings. Per Nickís request sent email noting the differences. Continued drawing nose rib blocks. Used new dimensions, as (after careful study) they correct a discrepancy in the original drawings that made the rib blocks S6-S8 the wrong length. Each rib should be 39mm shorter than the previous; this was not so with the original drawings. Completed S7-S9 drawings.
