The MAS series of dangerously low fuel emergencies into Heathrow lead to bare faced denials and cover ups by MAS. UK authorities couldn't rely on assurances given and in the end had to insist that MAS provided weekly reports on fuel levels of aircraft arriving into the UK as a condition of being allowed to fly there.
With the present incident on home soil you'll find commercial aviation and military interests are far too buddy buddy to expect leaks to filter into the public domain.
