And – apart from nerves of steel – you would think that an air traffic controller would also need perfect 20-20 vision.
But not on the Scilly Isles, where a position has just been advertised with a job application form also available in Braille.
The airport on St Mary's is owned and operated by the Council of the Isles of Scilly, who insist they are simply following equal opportunities procedures.
But many say it is absurd and a symptom of political correctness gone mad.
“It's just common sense that you would not employ an air traffic controller who is blind or partially sighted,” said one insider on the island's aviation sector.
“It's just one of those things they have got to put on forms. It's got to go on everything these days whether it's relevant or not.”
Yes, if you are blind you can now apply for a job as an air traffic controller in the Scilly Island. I can not stress how bad this is. Isn't there radar or something you need to look at. Or at least be able to use a pair of binoculars. I predict nothing but fire and doom for future planes flying to and from the island. I am glad my mom (a stewardess) only flies to San Fransisco.
