Oxygen sequence (WO-type) Wolf-Rayet stars represent the final, brief phase in the evolution of the most massive stars prior to a SN explosion. They are characterised by extremely broad, high excitation oxygen and carbon emission lines in their UV and optical spectrum. Sand 2 in the LMC is the only single WO star for which far-UV FUSE observations of the 1032, 1038Å\ OVI resonance doublet are possible, and has the fastest continuous wind of any known star (~4,500 km/s!). We will carry out a spectral synthesis of FUSE observations of Sand 2 using state-of-the-art models -- supplemented by UV HST and ground-based MSSSO optical spectroscopy -- to help address the exact evolutionary status of WO stars.
