2011 will forever be remembered as the year Red 4 - Flt Lt Jon Egging - was killed when his jet crashed as the Red Arrows returned to Bournemouth airport.
Since those tragic events of Aug 20, Bournemouth and the Red Arrows have been inextricably linked. No-one who lives in the town or was there that day will ever forget.
Flowers were piled outside the town hall in an impromptu memorial that kept growing and growing.
The 2011 Bournemouth Air Festival had begun with chaos. Torrential rain hit the town just as the launch event was being held on Thursday morning.
It flooded the gardens in minutes and put paid to any prospect of flying displays that day.
But, 24 hours later, the rain was a distant memory and the sun was out. An epic clear-up operation by the council's dedicated workers meant everything was ready to go.
Then, after a stunning display on Saturday afternoon, Red Arrows pilot Flt Lt Jon Egging died after succumbing to g-force impairment as the team returned to Bournemouth Airport.
"Eight Red Arrow jets stood motionless on the runway for what seemed an age, waiting in vain for their ninth member to come home", wrote reporter Jim Durkin, from the airport.
Shocked festival-goers started laying flowers outside Bournemouth Town Hall, where a book of condolence was also opened.
The pilots expressed a wish to continue with Sunday's other displays and thousands wore red in tribute to the fallen Red 4 and his now-grounded team. Flags flew at half-mast.
It would be another year before the permanent Jon Egging Memorial, situated just along from the central air festival display line on the East Overcliff, was installed, cementing a relationship forged from shock and grief.
Bournemouth will forever have a special place in its heart for the Arrows, for Jon's widow Emma, and his mum Dawn.
