The otters are keeping an eye on interesting events in Singapore.

This time, they have their eyes set on the flying taxis that are in town this week for the International Transport Systems World Congress.

German startup, Volocopter, has brought in the flying taxis.

They look like helicopters but with 18 rotors and electrically-powered.

Volocopter is also displaying the take-off and landing site, called VoloPort, at the Marina Bay Floating Platform between Oct. 21 and 25, 2019.

Five otters were spotted at the floating platform on Oct. 21, catching a glimpse of the VoloPort and an unmanned flying taxi.

For those who want to catch a glimpse of a test flight, there will be one tomorrow (Oct. 22) at noontime.
