quoting from the bbc
A Flybe spokeswoman said: "On Monday morning, Flybe flight BE7220 from Manchester to Edinburgh landed without incident at 0750 after reporting a technical fault with the aircraft.
"This resulted in a warning light showing on the control panel. Engineers are investigating the fault and the aircraft is expected to resume its normal flying pattern this afternoon.
surely after such an incident it would be grounded for more than a few hours?
