Task: Question Generation
Input (English): Passage: The newspaper Aftonbladet had supplied the pigeons, bred in northern Norway with the optimistic hope that they would manage to return there, and their message cylinders contained pre-printed instructions in Norwegian asking the finder to pass the messages on to the newspaper's address in Stockholm. Andrée released at least four pigeons, but only one was ever retrieved, by a Norwegian steamer where the pigeon had alighted and been promptly shot. Its message is dated 13 July and gives the travel direction at that point as East by 10° South. The message reads: "The Andree Polar Expedition to the "Aftonbladet", Stockholm. 13 July, 12.30 p.m., 82 deg. north latitude, 15 deg. 5 min. east longitude. Good journey eastwards, 10 deg. south. All goes well on board. This is the third message sent by pigeon. Andree."
Lundström and others note that all three messages fail to mention the accident at takeoff, or the increasingly desperate situation, which Andrée described fully in his main diary. The balloon was out of equilibrium, sailing much too high and thereby losing hydrogen faster than even Nils Ekholm had feared, then repeatedly threatening to crash on the ice. It was weighed down by being rain-soaked ("dripping wet", writes Andrée in the diary), and the men were throwing all the sand and some of the payload overboard to keep it airborne.
Free flight lasted for 10 hours and 29 minutes and was followed by another 41 hours of bumpy riding with frequent ground contact before the inevitable final crash. The Eagle traveled for two days and three-and-a-half hours altogether, during which time, according to Andrée, none of the three men got any sleep. The definitive landing appears to have been gentle. Neither the men nor the homing pigeons in their wicker cages were hurt, and none of the equipment was damaged, not even the delicate optical instruments and Strindberg's two cameras.
Output (English): What was the name of the item that was in an accident at takeoff?
