Who was the first female skater to land the triple axel?
Axel jump
In addition, an Axel entrance can be used as a take-off for flying spins.  An Axel sit spin is also known as a flying reverse sit spin, and is essentially an Axel jump landed in a back sit spin.  Rarely, skaters may also attempt a double Axel sit spin.  In a flying open Axel sit spin, also known as a death drop, the skater achieves an almost horizontal position in the air (by kicking the takeoff leg backwards and to the side, instead of bringing it forward) before landing in a back sit spin.
