Abstract: The VLT-FLAMES Tarantula Survey is a multi-epoch spectroscopic campaign targeting ∼800 of the most massive stars in the 30 Dor region of the Large Magellanic Cloud. The dataset comprises well over 300 O-type stars, including 20 Of/WN and Wolf-Rayet stars. A survey of this type has a large potential for serendipitous discoveries. We discuss three intriguing findings in the subset of O and WNh stars obtained in the first year of data analysis: (i) VFTS 682, the first ∼150 M star that is not located in the core of a massive star cluster; (ii) VFTS 102, a near-critically spinning O9 V star, and (iii) R139, found to be the most massive binary system where both components are O supergiants.
