The possibility of dislocating a knee during take-off and the instability of the paramotor were all contributing factors....

A more trivial but still significant moment was the realisation that a swan had perished after going missing. Whilst not a huge logistical setback, it was still an emotionally powerful moment for Dench

While being homesick, she had grown quite attached to the swans

Therefore, losing track of the swans is inevitable and saddening as Sacha got emotionally attached to them - possibly due to the lack of civilization

When flying, the temperatures will drop and she cannot stay warm by moving her arms because it destabilizes the paraglider

On the other hand, she had concerns of disturbing other migrating birds, also having to deal with uneducated, Russian children who hunt for migrating birds

A 7000 km journey, frigidly cold temperatures and doing it all from a swan's perspective are factors making the journey challenging

She spent her time in a hospital getting a MRI. Additionally, she had dislocated her knee during a take-off

These have increased the difficulty of positioning the swans as well as hindered conservation and research.

The cold temperatures during the journey was tough
