A memorial service has been held for a Cambridge woman who died when a Boeing airliner crashed near the Russian city of Kazan.
Hundreds of people were at the service for Donna Bull, 53, at Great St Mary's Church, Cambridge.
All 44 passengers and six crew died when the Boeing 737 exploded on impact while trying to land at Kazan airport in November.
Close friend Rebecca Stott said Mrs Bull was "an amazing person".
Mrs Bull was a member of the city's Champion of the Thames rowing club, and rowers made an arch of rowing blades at the church entrance.
She was a teacher at Bellerbys College, and current and former students attended the memorial.
After the service there was a procession to the River Cam, where 53 paper boats with candles - one for each year of Mrs Bull's life - were released on to the water.
Mrs Bull leaves behind a partner, Bob Crome, and two children, Kate, 19, and 18-year-old George.
She had been travelling to Kazan for the start of a 10-day marketing trip.
Her Moscow-based colleague Yana Baranova, with whom she was travelling, also died in the crash.
