The Red Arrows, Britain's RAF aerobatic team, perform their public display over a lake and boating landscape. A family stay still below the elite team as they perform their display on one of the UK's most beautiful locations in norhern England. The team are using the lake as a reference point as display datum (centre) during their display, a show-stopping manoeuvre of their 25-minute air show display routine. 'Datum' is an axis on which the Red Arrows focus their displays, from where the whole show is visible at the crowd's centre. The lake is but one of a series of datum points selected by the team leader as a geographical point from which to navigate. Since 1965 the squadron have flown over 4,000 shows in 52 countries and are an important part of Britain's summer events where aerobatics aircraft perform their manoeuvres in front of massed crowds.
