The Yankee Air Museum received a letter from publishers of the Guinness Book of World Records indicating that "you have successfully achieved a new Guinness World Records title for 'largest gathering of people dressed as Rosie the Riveter'".
The museum still needs to raise about $1.25 million by May 1st to save a portion of the plant to use as its new home.
