Hi,
Though we know differently, the grounding of an aircraft is a flight safety matter, not a legal, economic or political matter.
Are you sure you can discard the factor "economic" (and BTW .. economic can be linked with "politic")so surely from a decision or not to ground a type of aircraft ?
It was not easy to ground the Concorde .. and in fact this plane was a economic disaster in exploitation .. so it was not a great lost for AF and BA .. just a lost of "prestige"..
For the Airbus type .. it's completely different.
Imagine all the A330 and 340 grounded ...
Who will have the "balls" for take such decision if necessary ?
Bye.
