Remember 'Swan woman' Sacha Dench? She's the woman who’s making the world’s first attempt to follow migrating swans by air.
Well now a team of volunteers have set off from Slimbridge in Gloucestershire headed for Arkhangelsk, Russia, where they will meet up with Sacha.
The team includes a medic, a mechanic, a journalist, a photographer and two cameramen. Together they will support Sacha Dench from the ground as she flies 7,000km across 11 countries in a powered paraglider.
Along the way they will meet the people who the swans cross paths with each year, and investigate the dramatic decline in the swan population that has happened over the last two decades.
They will highlight the perils and wonders of the incredible journey that the birds complete twice a year, starting from just a few months old.
You'll be able to follow their progress here.
Sacha Dench is currently in the far north of Russia near the Bewick’s swans’ breeding grounds, waiting for weather conditions to trigger their migration.
Once they depart, she will follow their route across the tundra, stopping to refuel and rest at hunters’ huts along the coast, until she reaches the support team in Arkhangelsk.
Sacha and the team will broadcast regular video updates live from the expedition on www.flightoftheswans.org.
