No Department for Transport or Downing Street confirmation on gov.uk and no ministerial statement in Hansard said Nats had handed over the report on or before 16 September 2026; Hansard records zero NATS contributions, written statements or written answers between 15 and 22 September, and the last mention is Lord Hendy telling the Lords on 14 September that the Nats report was still "due on Wednesday". Heidi Alexander first said she "had received Nats' report" on 18 September 2026, two days after the deadline and a day after the market's own resolve date.
The report market resolves on a Department for Transport or Downing Street confirmation on gov.uk, or a ministerial statement recorded in Hansard, that Nats has handed over the report ordered on 9 September. It resolves YES if delivery is confirmed on or before 16 September 2026, whether or not the text is published; an interim submission the government describes as the requested report counts, while a request for more time resolves NO. BBC News and the Guardian settle it if no statement appears.
We looked for system failures at air traffic control operators in the UK, Europe and the US since 2014 that cancelled or delayed flights at scale. We checked whether the head of the operator was still in the job 30 days later. We found seven, and in all seven the head stayed. Three of them were at Nats itself.
