Alistair (The Time of Angels)
From Tardis Wiki, the free Doctor Who reference
Alistair (The Time of Angels) was a presumed acquaintance of Professor River Song for whom he had danced with in the past. When River escaped from the Byzantium to land in the TARDIS, the air pressure forced Alistair to hold onto a nearby pipe so that he did not fall out into space. The Byzantium later crashed. This crash presumably killed Alistair.
