Ben Bowie and Sophie Knight were just meters apart, but have never met, until now.
The sister of a man killed in the Shoreham Airshow disaster told the BBC that her father never accepted that he could have prevented his son's death.
Denise Morris' brother, Mark Reeves, 53, was killed while riding his motorbike to the event on 22 August.
She said her father could not come to terms with declining his son's invite to attend the show - believing this might have saved his life as they would have gone together in a car.
"Horrific things happen to people every day around the world," Ms Morris said.
"But you never dream it's going to be you, your family or someone you love."

A couple whose son died in the Shoreham air crash are calling for the Civil Aviation Authority (CAA) to be held accountable for safety at the event.
Matthew Grimstone, a Worthing United footballer, was travelling on the A27 when the plane crashed.
His parents, Phil and Sue Grimstone, believe the public's safety was compromised and ignored at the expense of the show going ahead ten years ago.
Rob Bishton, chief executive at the CAA, said: "Airshows continue to be subject to rigorous oversight to ensure the highest possible safety standards are maintained."
Brighton & Hove Albion have released a video tribute to mark the 10th anniversary of the Shoreham air crash.
One of the 11 men that died in August 2015 was Albion staff member Matthew Grimstone. Jacob Schilt, who Mr Grimstone was travelling with, also lost his life. Both had close links to the club.
Clubs across Sussex held a minute silence in their next matches to pay tribute to those who lost their life in the crash.
Brighton & Hove Albion won their next two league matches, away at Ipswich Town and at home to Hull City.
After the win at Ipswich, goalscorer Kazenga LuaLua said the win "was for them".
On a quiet summer afternoon, the skies above Shoreham filled with smoke and sorrow.

Many of the emergency service workers who attended the Shoreham air crash were local people and were deeply affected by what they saw.
Jill Simpson, a senior chaplain for South East Coast Ambulance Service, was on hand to lend support 10 years ago and has continued to do so in the intervening years.
She said: "It was like waves that were rippling out.
"Everybody seemed to know somebody who was a relative of someone who had died."
At 13:22 BST, the exact time when the plane crashed ten years ago, a public commemoration took place at the memorial by the River Adur in Shoreham.
The names of the 11 men who died were read out, followed by a two-minute silence.
Flowers were laid by relatives, friends and those affected by the tragedy's events.
A total of 11 doves were also released in tribute.

The community in the Shoreham area responded with an outpouring of kindness in the aftermath of the air crash.
Neil Parkin, the former leader of Adur District Council, said people came from all over to lay flowers and donate food and drink.
"It took over the whole foyer of the Civic Centre, people were bringing cakes and drinks for the workers," he said.
"There was a lot of love out there and a lot of feeling."
Those who witnessed of the Shoreham air crash are still coming to terms with what they saw 10 years on.
BBC South East brought two eyewitnesses together, who were extremely close to the crash, to compare their experiences on 22 August 2015 and in the following years.
Sophia Knight, who was on her motorbike, said she remembered feeling "absolutely incredibly awed".
Ben Bowie, who witnessed the disaster with his family from their camper van, said: "There was a huge explosion and we were all screaming."
It was at this moment - at 13:22 on 22 August 2015 - that a jet crashed on to the A27 in Shoreham, killing 11 men.
A two-minute silence will now take place to pay respects to those who lost their lives.

Football clubs across Sussex have come together every year since the Shoreham air disaster to show support for two players who died in the crash.
Matthew Grimstone and Jacob Schilt, both 23, were travelling in the same car on their way to play for Worthing United FC when the plane crashed onto the A27.
To mark 10 years since they died, a day of friendly fixtures was held in their memory at the Sussex FA headquarters in Lancing.
Paul Grimstone, Matthew's older brother, said: "He loved football, and being close to the game allows us to be close to him as well."
A senior nurse has written a poem in memory of her friend and colleague Tony Brightwell, one of the eleven people who died.
Gabrielle Munslow, a senior mental health nurse practitioner, worked with Mr Brightwell in the East Brighton older people community mental health team, where he was a care manager.
She said: "Tony always looked out for the whole team, making sure no one was left without support.
"Losing him was a terrible shock to the team and was felt by many people."
Her poem, titled Torn by the Sky, can be read here, external.

Feelings of horror, grief and helplessness found an outlet in the aftermath of the air crash as flowers were laid on a wooden bridge in Shoreham.
County archivist for West Sussex, Wendy Walker, and her team devised a plan to save the countless messages that were left.
She said: "When something terrible like this happens, everybody wants to know what they can do to help, and we felt this was what we could do.
"Meeting the families and hearing their stories and showing them the archive is something I won't forget."
Kelly and Marina Polito and Denise Morris talk about their memories of their brothers.

The church where the service is taking place is full, with all 150 seats taken.
Families of those who died say this is the largest gathering of relatives and friends of victims since the tragedy.
As part of the service, members of the congregation will be asked if they want to light a candle to remember loved ones, or as a way of personally commemorating the anniversary.
Families of those killed in the Shoreham Airshow crash have recalled their "despair and disbelief" 10 years on.
Kelly Will, whose 23-year-old brother Daniele Polito died in the disaster, said she had moved to the US two weeks before when her mother called with the news.
"She was just crying down the phone, blurting it out in such terror and torment," she said.
Ms Will told the BBC: "I can't even express the feelings and words.. to hear that feeling of absolute anguish."

A memorial football match has taken place every year in honour of two men killed in the Shoreham air crash.
Worthing United FC players Jacob Schilt and Matthew Grimstone were on their way to a match when the jet crashed onto the A27 during the Shoreham Air Show in August 2015.
The 23-year-olds were among 11 men who lost their lives in the incident.
The annual match, which took place in June this year, was between the pair's former primary schools, Balfour and Patcham, in Brighton.

Roy Barraclough, from West Sussex Fire & Rescue Service, was on the scene on the day of the air crash.
On Friday morning, he told BBC Radio Sussex: "I was attending the airshow as a duty officer and the incident happened as I was inside my vehicle.
"It is very difficult to fully describe the scene as it not something that is describable in a day-to-day feeling.
"From that warm, sunny day, the area was full of smoke and devastation. It was a very difficult situation and very complex."
