4 - 3
Stansted 4 Clapton 3
Clapton slumped to a fifth successive defeat after letting a 3-0 lead slip at Hargrave Park.
The visitors were in superb form in the first half and Nathan Cook netted their third goal on 35 minutes to seemingly secure the points.
But the Airportmen took off after the restart, netting four unanswered goals to turn the match on its head and claim victory that moved them level on points with Tons in mid-table.
Substitute Thomas Lakin began the fightback midway through the second half, with Tom Hollanby netting Stansted’s second soon after.
Matthew Ashwell levelled things up on 80 minutes, just two minutes after coming off the bench, and David Ratcliffe struck the winner with one minute left in normal time.
