Passengers watched in terror as two Ryanair planes crashed into each other on the runway at Dublin airport.
The Boeing 737s collided this morning - causing part of the wing of one plane to break off as it hit the tail of the other.
The planes were taxiing on the runway when the crash happened, the Irish airline said.
But a spokesman emphasised that the collision was only a "minor incident".
Passenger Emily Carroll took pictures of the crash aftermath and posted them on Twitter.
She wrote: "Stuck on a Ryanair plane Dublin Airport clashed with another plane en route to runway. Lost top of our wing!"
People on board were forced to get off the planes and take alternative flights to Brussels Charleroi and Edinburgh.
A spokesperson for Ryanair said there was "no impact to customers on board" the planes and said Irish Aviation Authority (IAA) was investigating the accident.
In a statement, the company said: “Two of our aircraft were taxiing slowly to the runway at Dublin Airport this morning. The winglet of one aircraft appears to have scraped the tail of the other. Both aircraft were under the instruction of Dublin Airport Air Traffic Control at the time.
"There was no impact on customers on board and Ryanair contacted the IAA and worked with them to return both aircraft to stand. Affected customers disembarked, were provided with refreshment vouchers and boarded two replacement aircraft, which departed to Brussels Charleroi and Edinburgh later this morning."
It added: "Ryanair apologises sincerely to customers for any inconvenience. Both aircraft are being repaired by Ryanair engineers and will be returned to service shortly.”
A spokesman for the IAA said Dublin airport was experiencing minor delays following the inicident.
He said: "The Air Accident Investigation Unit (AAIU) of the Department of Transport, Tourism and Sport has been notified and will conduct a further investigation".
