Defiant protesters demanded the resignation of Transport Minister Alistair Darling over controversial plans for Birmingham International Airport's second runway.
At a heated meeting last night, campaigners vowed to fight on and called for a re-run of the consultation process.
And they insisted that the Government's decision was not a done deal.
If follows Solihull Council's decision not to pursue a judicial review into plans to build a second runway, announced last December.
The consultation was set up to look into new airport capacity to meet the expected demand in air travel over the next 30 years.
Birmingham Airport Anti-Noise Group (BANG) said the apparently limited expansion plans were deceptive and the airport would be the size of Heathrow by 2030.
BANG campaigner Brett Rehling, from Birmingham Friends of the Earth said: "People think it's a done deal but its not.
"People need to know that the decision for this second airport impacts on them and could be taking the chimney-tops off their rooves.
"Everyone is undoubtedly campaign-weary but we have to work together to get a re-run of the consultation process and make our voices heard."
During the consultation process, BIA suggested a second runway and it was this proposal that the Government favoured.
Councillor Jim Ryan said: "My beef is not with airport or airport managers but with the council and the Government - Darling should go."
James Bothan, secretary of BANG, said: "There's a real danger of Birmingham becoming the forgotten casualty of the air industry's insatiable demand."
