In this July 17, 2013, file photo, part of the former Willow Run Bomber Plant stands in Ypsilanti Township, Mich. A group wants to preserve a portion of the plant and house a museum there dedicated to aviation and the countless Rosies across the country. Save the Bomber Plant officials have until Thursday, May 1, to raise the remainder of the $8 million needed to save the plant from demolition.

DETROIT — Organizers of an effort to save from demolition a portion of the Michigan factory where Rosie the Riveter worked say they have accomplished their goal.

Or at least part of it.

The site's manager had given the Save the Willow Run Bomber Plant campaign a deadline of Thursday to raise the $8 million needed to buy a 150,000-square-foot slice of the old factory for use as a museum.

Fundraising consultant Michael Montgomery says the group is close to having the full amount and has enough to go forward with a purchase agreement for the property. The deal is expected to be finalized in seven to 10 days.

Meanwhile, Montgomery says he and others will keep working to raise cash to put toward making the new Yankee Air Museum a reality.
