The effort to bring home a Halifax Bomber from the bottom of the sea off the Swedish coast will extend into next Spring and Summer.

Poor weather hindered efforts to raise the World War II airplane off the sea floor and return it to the Bomber Command Museum in Nanton this year.

Museum Director Karl Kjarsgaard with one of the seven Halifax engines in their possession. The one here is one of two he calls "no time." Which means they're brand new and have never been run, despite being manufactured close to 80 years ago.

Museum Director Karl Kjarsgaard says the biggest hurdle is moving the sand around the wreckage.

"It's been there 74 years, and it's sifted into the sand. But we're determined, but the old saying of "Adversity is the mother of invention" is hard at work. We have a plan "B" and a plan "C." So, we're going ahead with it to get a Halifax for the Bomber Command Museum in Nanton."

Kjarsgaard says they hope to be back diving at the site by next Spring, with the airframe and other parts salvaged off the sea floor before the year's end, then returned to Nanton for the long process of piecing them back together and into a running display like the Lancaster they already have on display.
