[5] The wrapping was brown (green in the mint version) and displayed the "Rowntree's" script logo and the large word "AERO", along with the slogan "Hold on tight or I'll fly away!"

The vintage packaging from the Nestlé UK & Ireland Archive was later released[6] as a "reminiscence pack" on advice from the Alzheimer's Society.

[8] During July 1983, the heatwave in the United Kingdom caused the bubbles in Aero bars to collapse due to the chocolate melting.

[10] In 2004, three workers at the York factory were dismissed for intentionally misprinting rude messages on the packaging of 20 pallets of Aero bars.

[15] In February 2015, York's Chocolate Story museum celebrated the 80th anniversary of the launch of the Aero bar with demonstrations and activities.

[20] In 2011, Nestlé recommenced manufacturing Aero bars in Australia at their Campbellfield factory in Victoria, with a capacity of up to 1000 tonnes per year.

[24] In 1998, amateur rocket enthusiast Derek Willis was eating an Aero bar and was inspired by the bubbles to create the low-cost fuel, Asprop (Aerated Solid Propellant).

[25] In 2007, an observational study published in the British Medical Journal explored the use of the texture of Aero and Crunchie bars as a technique to explain bone structure to patients.

The MuCell plastic is injected with gas bubbles during moulding, making a microscopic honeycomb-like structure that is twenty per cent lighter and so lowers fuel consumption.

[1] Advertising about the imported bars in Melbourne, Australia in 1938 announced the Aero as the "...original English aerated milk chocolate... ...crisp, light and yet so sustaining".

The relaunch campaign had commissioned oil paintings of 40 "ordinary" women, to highlight that the chocolate bars were an accessible treat for all.

[35] Some of the models were later identified as Barbara Pitt,[36] Janey Ironside, Rose Wylie,[37] Myrtle Crawford (later, Lady Acland)[38] and Pamela Synge.

[40] In the late 1980s, the slogan "Each Aero Chocolate Bar Has The Nourishment Of Almost Three Ounces Of Milk" was created by Toronto advertiser John Straiton.

[41] In 1987, the advertisement won the Rotten Apple Award from the Quebec Corporation of Professional Dietitians, as the comparison between the nutritional benefit of confectionery and dairy was considered misleading.

[45] In 1996, Nestlé repackaged the Aero bar and relaunched it with television advertising that used voice-over by Dani Behr, and the phrase "Great chocolate taste."

[55] The promotional campaign included people in mouse costumes in Manchester providing passers-by with a hula-hoop challenge in exchange for a free Aero bar.

[56] In July 2001, presenter Davina McCall accidentally promoted Aero during a live eviction episode of Big Brother UK.

[57] In 2002, Nestlé Canada's research showed that consumers would often break the Aero bar into pieces and then let it melt in the mouth to prolong the experience.

[59] In 2009, skateboarder Bob Burnquist featured in a UK ad called "feel the bubbles", filmed skating through chocolate coloured balloons, with the Jackson 5's song ABC playing in the background.

[60] The slogan in 2011 was "Irresistabubble"—a revival of a 1980s campaign that also featured the same word, and was created by Salman Rushdie, during his time as an advertising copywriter.

[62] In 2012, agency Skive created the 'AeroMail' social media campaign in which consumers could "spread the bubbliness" of Aero with a digital balloon on Facebook.

[63] In 2018, The Interflex Group won the "Best use of process colours only" in the FlexoTech Awards for their work on the Nestlé Aero Chocolate Bubbles print design.
