 The shed was extended in 1926 and its roof was raised to accommodate the R101.A second shed was moved here from RNAS Pulham, Norfolk, in 1928, but after the crash of the R101 in 1930, all work stopped in Britain on airships and the site became a storage station.It became known as RAF Cardington in 1936 and started building barrage balloons and became the No 1 RAF Balloon Training Unit.
