30 white rhinos were loaded onto an airplane over the weekend and flown from South Africa to Rwanda.

The distance between South Africa and Rwanda is about 4,268.3 kilometers or 2,652.1 miles.

In other words, that’s about a 13-hour plane ride.

This is considered the biggest-ever translocation of the 1.50-ton animals.

All the rhinos were slightly sedated to keep them calm and not aggressive or trying to get out of the crates.

The move of 30 rhinos took three years to organize and involved more than 60 tons of giant mammals and their supplies.

The history-making move was part of an unprecedented conservation mission to protect the near-threatened species from poachers and spread them across the continent.

19 females and 11 males were rehomed at the Akagera national park.

The conservation group, African Parks, hopes to breed and strengthen the species while they’re in the park.
