2011 Red Arrows ejection

Thanks!

Not really ‘historic’ 😉 but;

The accident report was published in 2014: https://www.gov.uk/government/publications/service-inquiry-into-the-accident-involving-hawk-tmk1-xx177.

It takes some wading through, but the important conclusions can be found on page 68 of the third pdf of section 1.4: Analysis and findings.
