One of two observation balloons procured by Robert Falcon Scott from the the British War Office for him to use on his first polar expedition. Inflated with 8480 cubic feet (240 m³) of hydrogen and ascended with Capt. Scott on February 4, 1902, this was the first flight in Antarctica by any type of aircraft and reached a height of 244 metres - the limit of the tether. From the balloon Capt. Scott saw many parallel lines of undulation to Southward. A second ascent was then made the same day, carrying Ernest Shackleton, who took the first ever Antarctic aerial photographs, but after that the balloon developed a leak and was never flown again. The location of these flights was a small bay in the Ross Ice Barrier, near King Edward VII Land along what is now known as the Bay of Whales. The second balloon of the expedition was never flown. The name “Eva” was given to the former British Army balloon by Scott.
