One for the camera and/or maths buffs

An object approximately 75 feet long by 50 feet wide is visible 81,000 feet away and occupies approximately 1/16th of the total frame on a TV camera (16:9 aspect ratio).

Approximately what zoom lens would this require?

PS - I realise this information is incomplete - your best guess will be fine as this is only to satisfy my curiosity.
