Passengers have spoken of their terror as smoke filled the cabin of their plane just before take-off and it was brought to a shuddering halt on the runway at Glasgow Airport.
They said the pilot of the Jet2 aircraft slammed on the brakes before the 189 passengers were evacuated using inflatable chutes.
The incident happened on a 737 plane bound for Alicante, Spain at about 7.40am.
Strathclyde Police said five people were taken to the Royal Alexandra Hospital in Paisley and a further 15 were treated at the scene. No one was seriously injured.
Passenger Jean Walker said some people had to jump from the aircraft wing to the ground.
She said: "It was terrifying. We were about to take off and the plane started shuddering and there were lights flashing and smoke and the crew started shouting 'Get out, get out'.
"We were sitting at the wing and the girl opened the door and we went out on the wing, but there wasn't a chute there.
"There were about eight or 10 of us on the wing and I was saying people couldn't come out because there was no chute.
"Two girls jumped off the wing on to the ground. They were OK.
"Other people got hurt coming down the chutes - they were inflated, but the hostesses were just shouting 'Jump, jump' and people were just banging into each other at the bottom, and about four people were taken to hospital."
Her husband Gordon Walker said: "You better believe it was terrifying.
"The stewardesses were panicking and shouting (at) people to go one way, then the other. It all happened really quick and I've never seen anything like it."
Glasgow Airport said flights were suspended until 10am but the runway has since reopened.
Six inbound flights were diverted and 19 others were cancelled or delayed.
Earlier this month, around 60 passengers had to evacuate a Thomas Cook plane by emergency chutes when the cabin filled with smoke after landing at Glasgow.
The flight from Dalaman, Turkey, touched down on October 11 as normal and was on the stand when the incident happened.
In a separate incident, a passenger plane made an emergency landing at Dublin Airport after crew detected smoke in the cockpit.
The Thomas Cook flight, from Manchester to Tenerife, landed at 9.40am and passengers were safely evacuated.
