Oslo, Norway, March 28—(AP)—Preparations for the Amundsen-Ellsworth Polar Flight in May are nearing the final stage. On a hill just outside Oslo a mooring mast nearly one hundred feet high has been erected for the airship “Norge,” in which the flight is to be made. The dirigible, constructed in Italy, is now being inspected by Captain Roald Amundsen, who arrived in Rome for that purpose last Friday, it will soon be brought from Rome to Oslo.

The auxiliary vessel “Hobby,” which was used in the Polar flight of 1925, has left Trondhjem for Svalbardi (the new Norwegian name for Spitzbergen), with equipment or the expedition, consisting of material for the mooring mast at King’s Bay and hydrogen for the airship. A hangar has already been completed at King’s Bay.
