Here is footage of the moment a Sunderland house exploded in a suspected gas blast.
It was caught on camera by a neighbour's CCTV system in Rosslyn Avenue, Ryhope, Sunderland, and is broadcast here with their permission.
The sound of the explosion at 8.48am could be heard more than a mile away in Grangetown, Hill View and Hendon.
The only person inside the property at the time of the blast, Susan Shepherd, 40, suffered burns to her upper body and an injury to her hip.
She was taken by air ambulance to Newcastle Royal Infirmary in a "serious but stable condition".
Air Hostess, Kelly Ricketts, 26, who supplied the footage, said: "I work as cabin crew and we had flown into Manchester.
"When we landed and I turned my phone on, I had lots of messages on my phone asking if I was okay but I had no idea what was going on.
"I phoned my mam as we live 10 doors down from where it happened and she told me what had happened.
"Our CCTV is motion sensitive and the neighbour had just gone past and activated it so it was still recording when the blast happened.
"My dad drives past there on his motorbike on his way to work, if it happened 20 minutes earlier my dad might have been caught up in it all.
"All the debris has been cleaned up now and the area has been put behind security fencing.
"The gas people have been brilliant and have checked everything before allowing us back into our homes.
"This is not something you expect to happen to you, I'm just gald everyone is okay."
