Rosies in the Pacific Northwest numbered in the thousands, recruited by posters that said rivet work was easy - just like pinning a pattern on fabric to make a dress. Rosies helped boost airplane production at The Boeing Company from 60 per month in 1942 to an astounding 362 per month by March 1944. At one point, the Seattle plant rolled out 16 B-17 Flying Fortress bombers in 24 hours. The Rosies were working 12 hours a day, 7 days a week, so Boeing assisted working mothers in locating day care and provided work shifts that would allow them to be at home during the day.
