Utterly Butterly in the context of "AeroSuperBatics"

AeroSuperBatics Limited, legally known as Aero-Super-Batics Limited, and commonly known merely as AeroSuperBatics, is a British civilian biplane multi-aircraft formation aerobatics and wing walking team. They currently perform as The AeroSuperBatics Wingwalkers (unsponsored since 2018), and were branded as 'The Flying Circus' in 2018. They were previously branded Breitling 'Swiss Chronographs' (performing as The Breitling Wingwalkers, 2011 to 2018) in accordance with their sponsorship agreement with the Swiss watch manufacturer Breitling. Prior to that, branding included Guinot 'Institut Paris' (performing as Team Guinot, 2008 to 2009), Colt Cars, St.Ivel 'Utterly Butterly' (performing as The Utterly Butterlys, 1999 to 2007), Cadbury's 'Crunchie' (performing as the 'Crunchie Flying Circus', 1992 to 1998), and Yugo Cars, according to their commercial sponsors at the time. Their display options currently consist of either a solo aircraft, or a two-ship formation pair, or a three-ship display, and previously included a four-ship formation, and during the 2008 display season, a five-ship formation. They are the world's only formation wingwalking team.
