In his fascinating article on space junk, Ian Sample informs us that the radar tracking the debris in the UK is operated by the RAF (Mind that satellite! The mission to clean up dangerous space junk, 21 April). That is reassuring. He adds that it is “analysts from Serco” who interpret the data. Reading that made me feel like ducking for cover.

• As a born and bred Yorkshire lass, I would like to confirm that the correct phrase is “trouble at t’mill”. The t’ is the Yorkshire pronunciation of “the”. Perhaps it is different in Cheshire (Letters, 24 April)? In Yorkshire we use the definite article before a noun.
