Grounding aircraft on this scale over safety concerns is rare. The last time the FAA ordered a general grounding of an aircraft model was in 1979, when McDonnell Douglas DC-10s were grounded following a fatal crash.

All eight airlines currently flying Boeing 787s have grounded the planes:
All Nippon Airways and Japan Airways have grounded their combined fleet of 24 787s
United Airlines, the only US airline currently operating Dreamliners, said it would immediately comply with the FAA's directive and would begin re-accommodating customers on alternative aircraft
Chile's LAN announced it would suspend its three Dreamliners from service in co-ordination with the Chilean Aeronautical Authority
Indian aviation regulators ordered Air India to stop operating its 787s
Poland's Lot Airlines, the only European airline currently flying 787s, was due to launch its 787 transatlantic service this week, but cancelled a return flight from Chicago to Warsaw on Wednesday
Qatar Airways, which currently operates five Dreamliners, said it had grounded the planes and was "actively working with Boeing and the regulators to restore full customer confidence in the 787"
Ethiopian Airlines said it was taking its 787s out of service as a precautionary measure

Mr Francis said the safety concerns could have an effect on airlines currently considering ordering 787s, causing them to choose rival Airbus' A330 instead, which is a comparable aircraft and a proven product.
