The case for a third runway at Heathrow will be submitted today by bosses of the west London airport. The three options which will be presented include:
1) A third runway to the north west of airport which would require part of the M25 being put in a tunnel and affect the villages of Longford and Harmondsworth.
Passenger capacity: 130m. Cost: £17bn. Starts: 2026. Demolishes: 950 homes
2) A third runway to the south west of the airport which starts over Wraysbury and King George VI reservoirs. A section of the M25 would need to be reconfigured and tunnelled and the village of Stanwell Moor flattened.
Passenger capacity: 130m. Cost: £18bn. Starts: 2029. Demolishes: 850 homes
3) A third runway close to Sipson, Harlington and Cranford Cross. It would be a shorter length with fewer planes, the cheapest and quickest option but also the noisiest and the highest number of homes would be affected.
Passenger capacity: 123m. Cost: £14bn. Starts: 2025. Demolishes: 2,700 homes
Thousands of air travellers face delays after air traffic control company Nats experienced "technical problems" at its Hampshire control centre.
There will be delays, although we are not sure how long they will be.
The problem was at Nats' centre at Swanwick, near Southampton.
The company experienced some flight-affecting computer glitches when it first moved to the site about 10 years ago.
Air traffic control company Nats said it is restricting the number of aircraft flying across the south of England and those taking off from airports due to technical problems at its Swanwick control centre in Hampshire.
Jet2 chief executive Ian Doubtfire says an investigation will be carried out into what happened at Glasgow Airport today.
Passengers who were aboard this morning's cancelled flight to Alicante will be offered another flight at 3pm today.
Passenger Jean Walker said some people had to jump from the aircraft wing to the ground.
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'.
She said two women had to jump from the aircraft's wing because there was no escape chute available to her:
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.
The Scottish Ambulance Service said it was treating four passengers for chest and hip injuries.
Strathclyde Fire and Rescue said it sent three appliances to the scene.
Glasgow Airport expect the runway to remain closed for at least another hour following the evacuation of a Jet2 flight this morning.
So far 12 flights have been unable to take off from Glasgow and a number of others have been diverted to Edinburgh.
There are reports of four people being treated for minor injuries, thought to have been sustained when using emergency chutes.
Aircraft passenger Barry Gemmell, who tweeted a picture of the Jet2 aircraft shortly after he says he disembarked, says three people have taken away in ambulances.
A statement from Jet2 said:
This morning's flight LS177 from Glasgow Airport to Alicante made an emergency stop on the runway just prior to take-off.
The aircraft was forced to curtail take-off due to smoke in the cabin.
All 189 passengers have disembarked the aircraft.
