The storm brewing around budget airline Ryanair continued on Tuesday, with the airline's chief executive branding a pilots' group which raised concerns a "joke".
The airline's share price rose by around 2 percent in trading Tuesday morning, after falling by 4.5 percent on Monday.
On Monday night, British broadcaster Channel 4 showed a program which alleged that pilots for Ryanair had "deep-rooted" concerns over the safety of the airline. The program, called Ryanair: Secrets from the Cockpit - Channel 4 Dispatches, raised serious concerns that the airline's employment practices could have an impact on passenger safety.
The program used a survey conducted by the Ryanair Pilot Group which claimed that 94 percent of more than 1,000 Ryanair pilots and first officers surveyed wanted regulators to conduct an inquiry into how working practices could affect safety at the airline.
