A plane landed with two more passengers that it had taken off with after a mother gave birth to twins on board. The passenger on the Russian flight went into labor unexpectedly.

Irina Vasylkova was 35 weeks pregnant when she got on the Polar Airlines from Zyryanka, in the East Russian Sakha Republic to Yakutsk, the capital city of the Sakha Republic. However shortly into the flight, the 25-year-old passenger started to go into labor, the Daily Mail reports.

When the flight crews realized what was happening, a flight attendant named Christina Kondratiev moved the young woman to a seat with more legroom at first. She tried to make her feel as relaxed as possible, in hopes that the woman could wait to deliver once the plane landed, however that wasn't the case.

"I told the pilot and he sped up the flight to make sure that we could arrive as early as possible, but it was clear that the delivery was not going to wait," Kondratiev said.

Realizing that the delivery was going to happen sooner than expected, the flight attendant had the pilot ask if there was any doctor on board the type AN-26 plane. Luckily there happened to be an obstetrician on board. The 47-year-old doctor named Elena Sleptcova stepped up and offered her services.

The first baby was born during the flight but the second was born just as the plane landed. The woman was wheeled into the arrivals terminal with twin girls in her arms.

The mother and her new two daughters were transported to a local hospital. All three are reportedly doing well. The new babies already got to meet their older sister, the 4-year-old Angelina.

To celebrate the joyous occasion, Polar Airlines is preparing gifts for the mother and twins. One of the gifts include free travel for life on any Polar Airlines flight.
