The RAF has joined the British Army in a bid to tackle the 20ft flames on Saddleworth Moor as the blaze rages on for the fifth day amid a blazing heatwave searing its way across Britain.
Helicopters have been pictured dropping gallons of water onto the flames in a bid to halt their spread, amid suggestions from locals that off-road motorcyclists riding the moorlands on Sunday ignited the blaze.
And 100 soldiers have also been sent to help the exhausted firefighters, the Ministry of Defence has confrimed.
The smoke engulfing homes has been described as dangerous with health officials forcing families to wear dust masks and to stay indoors.
The inferno has raged across four miles of the Pennines beauty spot near Greater Manchester, decimating the moorlands in its wake.
A major incident was declared yesterday morning as the blaze worsened, with 34 homes evacuated. A public health warning has now been issued about pollution in the air.
The task now facing crews is frequently shifting as changes in wind directions create fresh problem areas amid the ongoing heatwave, with temperatures reaching around 94F (33C) in the sun.
An RAF Chinook helicopter could soon be deployed to provide the military with the assistance requested, said Greater Manchester Fire and Rescue Service (GMFRS).
