This news anchor was expecting a clip of a tornado, and since this is a local news broadcast and on-air bloopers are their bread and butter, he got no clip of a tornado. Instead, he got a healthy dose of a space station, to which he responded, "There is no tornado in outer space."
Worst case scenario, they should've just played a clip from the Helen Hunt vehicle, "Twister." That would've sufficed.
