The RAF Displays held at Hendon between 1920 and 1937 were unique, in that no other air force attempted to project a vision of itself, its capabilities and its responsibilities in so public a way, on such a large scale and over such a long period. Of course, that's largely because there weren't many air forces around. Or rather, they did exist, but not independently of their nation's army and navy. Putting on such a big show was important for the RAF precisely because it was newborn: it needed to convince everyone (parliamentarians, journalists, the public, the other services, other nations) that it was necessary and/or that it was successful. Hendon seemed to have fulfilled this very well, judging by press attention and attendance numbers.
But viewed another way, the RAF Displays weren't unprecedented at all. Both the British Army and the Royal Navy had their own forms of public display. The Army had long performed in public, in fact, such ceremonies as trooping the colours, and the 19th century witnessed a huge growth in the popularity of military reviews, according to Scott Hughes Myerly 'the most popular and elaborate public manifestation of the military spectacle':
The action on the field consisted of evolutions of drill, musket volleys with blanks, and cannon salutes. Often a sham battle or mock, siege would be staged between two opposing units, or a bayonet or cavalry charge would be a part of the show.1
I'm not sure of the actual content of these mock battles, though the fact they they were performed during the Napoleonic Wars suggests an obvious ideological function. For its part, the Navy also developed fleet reviews into what Jan Rüger has termed 'a new form of public theatre'.2 This happened much later in the century, however, dramatically increasing in frequency after the review held for Victoria in 1887 on the occasion of her golden jubilee. By their nature, naval reviews afforded fewer opportunities for presenting narratives of actual combat. There were some, though, for example a 'mock-attack carried out by torpedo boats and submarines' at the 1909 Spithead review.3 Like the RAF later, and doubtless the Army before it, the Navy rather dubiously insisted that these were not mere spectacles but training for war.
Although Hendon itself was a pre-war site of aerial spectacle, that was a private enterprise and had nothing to do with the RFC (which probably would have been hard pressed to compete in qualitative terms anyway). So it was only after 1918 that it got into the game. The Navy held its first review in ten years in July 1924, shortly after the fifth Hendon, but as before the opportunities for creativity were limited. The Army began holding its own annual pageant in 1920, the Aldershot Command Searchlight Tattoo, a revival of an smaller event dating to the 1890s which now continued right up until the eve of war in 1939. There are many similarities with Hendon, which began the same year; the RAF seems to have even participated in Aldershot to some degree by providing aeroplanes as required. Like Hendon, Aldershot became very popular, growing from 22,000 spectators in 1922 to 300,000 by 1929 and gaining in social cachet.4 Again like Hendon, they were carefully choreographed and stage-managed, perhaps even more so -- there were systems of flashing lights backstage to give soldiers their cues and photographs were taken in rehearsal at 1 second intervals to see if anyone was out of step! But while there were some attempts in the early years to depict modern warfare, from 1925 the focus moved to historical re-enactments of the Army's past triumphs, especially Waterloo. So even as the Army was mechanising and experimenting in armoured warfare, to the public it chose to project an outdated style of warfare, dressing its men in redcoats rather than khaki. This is very different to the RAF's instincts when it came to public display, and it would be interesting to know what the reasons were. In any case, by dwelling on the past there was less chance of offending someone (apart from the French).
Another way to compare Hendon is internationally. Was there anything comparable to Hendon overseas? Yes, and Hendon seems to have been the direct inspiration. David Omissi notes that Italo Balbo, the senior Italian fascist, aviator and no mean impresario of aerial propaganda himself, attended Hendon in 1927 and 1932, declared that 'the RAF Display was the finest thing in aviation'.5 After he became Air Minister in 1929, he laid on two Giornata dell'ala, 'days of the wing', in 1930 and 1932, which sound very like Italian Hendons -- right down to mock air raids on Arab villages. But otherwise I don't know of anything quite like it. According to Peter Fritzsche, Germany had 'Carefully choreographed Nazi airshows' which attracted big crowds, but what messages they attempted to propagate beyond the obvious (i.e. airpower makes Germany powerful) is unclear.6 Maybe the Soviets? Scott Palmer has described in some detail Soviet airminded propaganda activities, but for the most part these revolved around big flights and agit-flights (that is, long distance record or proving flights and flying visits to remote villages). The exceptions, such as a 1927 'aerial parade in which more than three-dozen aircraft, flying in formation, spelled out the names of [Communist] Party luminaries' -- 'the largest aviation spectacle organized to date in the Soviet Union' -- don't seem to have involved anything like a Hendon set-piece.7 It's interesting that I'm reaching for comparisons with dictatorships here; they would seem to be the natural home for Hendon-like military aviation spectacles, and indeed the other democracies don't seem to have gone in for them. So what does that say about Britain and aviation between the wars?
It must say something, for Hendon wasn't the only form of official airminded propaganda in Britain -- far from it. The RAF was involved in a whole panoply of flying displays and other spectacles. It participated in flying displays put on by private flying clubs, such as the Birmingham Air Pageant in 1927 which had a hundred thousand visitors over two days.8 This included the bombing and destruction of a fake castle. A jubilee air review put on for George V in 1935 heralded more mass flypasts in the years of rearmament, helping to emphasise the RAF's strength of numbers.9 More significantly, in 1934 the first Empire Air Day was held at the suggestion of the Air League of the British Empire. This was the RAF's 'at home' day, where the public could visit their local military aerodrome and see what the flying life was like. Recruitment was surely a motivation, as perhaps was the desire to avoid a less-overtly warlike form of display (like Aldershot, Hendon was under increasing pressure from pacifists and the left for promoting militarism, especially to schoolchildren who were given free admission to the dress rehearsal). The latter concern may have curtailed the spread of displays resembling the Hendon set-pieces in the 1930s. As I discussed here recently, in 1924 and 1925 the RAF staged a mock aerial bombardment of London for the enjoyment of paying customers. The annual Air Defence of Great Britain (ADGB) exercises held between 1927 and 1931, which were public partly by virtue of being held around London and partly by being reported by accompanying journalists, were from 1932 held in more remote locations because they were too visible and open to misinterpretation, according to Tami Biddle.10 But it's possible that these types of practical propaganda simply transmuted into civil defence drills once ARP preparations began in 1935. The 1935 ADGB exercises, for example, involved practice blackouts in port cities like Chatham and Portsmouth, as Marc Wiggam explains, for the purpose of seeing how easy it was to hide a town in darkness rather than educating the public on how to prepare for air raids.11 This would necessarily involved aircraft flying overhead, playing the role of enemy bombers. But did RAF aircraft also take part in later, more civilian ARP exercises to increase their realism to the participants on the ground? That seems to have happened overseas, in Italy and Germany, but I'm not sure if it did in Britain.
There's lots to be done.
