As MHN reported in February, the Canadian Warplane Heritage Museum (CWHM) will be flying its famous Avro Lancaster bomber all the way to the U.K. this summer.

And now officials with the museum are hoping that one generous donor will pay $40,000 to ride along in the legendary war bird as it makes its much-anticipated flight across the pond.

Beginning on Aug. 8, the Canadian Lanc will execute the 3,900-mile (6,000-km) journey in series of hops that include one-day stopovers in Newfoundland, Greenland and Iceland. The final destination is RAF Corningsby, the home field of the only other airworthy Lancaster left in existence. The British bomber is part of the Battle of Britain Memorial Flight.

Once together, the sister planes will fly in formation at a series of late-summer events throughout Britain.

CWHM officials hope that the five-figure price tag for the coveted passenger seat on the 69-year-old Canadian-built aircraft will help offset the tremendous cost of the visit, which is expected to top $650,000.

“Going to England will be very special, but very expensive,” CWHM CEO David Rohrer told the Hamilton Spectator newspaper yesterday. “This trip is a major undertaking for the museum, so we have to come up with creative strategies to underwrite the cost of the trip.”

The ticket is currently up for grabs here on eBay.

But according to museum staff, there are certain conditions on who can join the crew for the historic voyage.

“Maximum weight is 250 pounds and you must be able to climb a ladder and manoeuvre in tight places,” says the online ad. “Winner must be willing to sign a photo waiver for the documentary filming.”

The top bidder will also be responsible for getting to the museum before take off, which is located at the Hamilton airport about an hour west of Toronto. And once in the United Kingdom, the winner will be on his or her own to get home.

The bidding ends on May 10, 2014 at 15:42 EDT.
