Lost.

TV  The BBC's live transmission of the 1947 production of Jack and the Beanstalk from the Croydon Grand was a logistical nightmare that led to innumerable problems:

"Monday evening, 6 January, came around, with the plan being to transmit the first half of the pantomime from 6.45 to 8.25pm. At 5.00pm that afternoon the OB transmitting van was working perfectly, but soon afterwards a fault appeared. According to a detailed technical report compiled in the wake of what he described as ‘a double disaster’, assistant chief engineer R. T. B. Wynn wrote, ‘This fault was intermittent [...] and conditions of darkness, weather and cramped space made the location of the fault and clearance of it extremely difficult.’ The whole broadcast was lost."
