This one is cut-n-dry in my opinion.
1. Continued approach below published minima.
2. Luckily the (blissfully unaware) passengers weren't harmed.
3. In essence the crew conspired to cover up their deed -
Both should have their licence/rating revoked. No room for cowboys in our work environment - I'm sure there are many more able and consciencious crew out there currently looking for work.
No bleeding heart boo hoos please. These guys are grade one idiots and should be grounded immediately.
