Depending on the logistical equipment available to any country serving its research stations, the options can include military transport, cargo transport, or extreme weather-capable equipment.
Access to Antarctica is usually by hull-reinforced ship or by long-distance airplanes.
Bipedal locomotion, snow cats, snow mobiles, airplanes, etc.
Yes, but not commercial airplanes.
Some governments use airplanes -- usually military aircraft -- for logistical support for their research stations on the continent. There are no commercial airplanes that fly to or from Antarctica. Airplanes function best when it's warmer there, usually between about October and about February. Otherwise jet fuel, lubricating oils, and mechanical systems are subject to freezing and not being able to operate as expected.
There are no paved runways in Antarctica. Airplanes land on skis, not wheels, on runways of ice.
Ships.
Antarctica is accessible part of the year by hull-reinforced ship, and by military logistics airplanes. In the past, some ships that sailed to the Antarctica were lost there, due to being crushed in the ice.
Airplanes make traveling to Antarctic easier.
No, FedEx does not fly to Antarctica. There is no commerce there to pay for FedEx services, nor is there any commercial air infrastructure to support commercial airplanes, anywhere on the continent.
There are no commercial airports in Antarctica. Most science stations, however, have ice runways nearby, so that airplanes servicing the station can land on skis.
Airplanes, Hovercraft's, Cars, Trucks, Helicopters........... Can go on forever....
Nobody did, because there were no successful airplanes then
