This is the dramatic moment helicopter crew members abseil SAS-style onto the roof of Manchester Central Fire Station.
The incredible footage was captured on Wednesday evening.
It's understood that two helicopters were involved in a training exercise.
Nearby residents in Ancoats describe seeing two 'military-style' helicopters circling over the fire station.
At least four people then descend from one of the choppers onto the flat roof of the building.
The crew members climb down a rope using a technique known as fast-roping.
One resident said the helicopters came within 'spitting distance' of his balcony.
He said: "I jumped out of my skin!"
Another person described seeing 'two blue thunder' helicopters landing near Oldham Road and then taking off again.
An SUV vehicle was seen taking the crew away from the scene almost immediately after they landed at the stataion.
Manchester Fire and Rescue Service confirmed that a training exercise took place at the fire station, but said it was not related to the fire service.
The Ministry of Defence have been contacted for a comment.
