gone for a burton
What does gone for a burton mean?
RAF euphemism for a pilot killed or shot down. Said with the stiff-upper-lip understatement of a generation that couldn't say 'dead' out loud. The aircrew slang equivalent of stepping out for a moment and never coming back.
Origin
RAF, WWII. Origin contested — most popular theory ties it to Burton's beer (Burton-upon-Trent, the brewing town); a pilot who'd 'gone for a Burton' was off having a pint, a gentle euphemism for not coming back. Other theories point to Montague Burton the tailor (gone to be measured for a suit, i.e. a coffin).
