From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Basil Airport is an airport in Nicky Town.
Basil Airport appeared in "Our Hero Awakes". The remaining citizens headed there to hide from Future Cell. Two people managed to successfully escape from Basil Airport while being chased by Imperfect Cell: a girl and her younger brother. In the English dub, the young boy's name was Tommy. They were both saved just in time by Kuririn, who fought against Future Cell bravely, but was quickly overpowered.
Piccolo and Tenshinhan reached the location of the fight before Cell killed Kuririn, however, therefore Future Cell fled. It is not known if the others managed to evade Future Cell also, as he hid there for some time after the Z Warriors had left.
