A strong wind threatened to make good football difficult, and although the vistitors had the elements in their favour in the opening half it was the hosts who took the lead.
David Dunn was short with a pass to Christ McGroarty, and Mark Gilhaney nipped in to cross for Aron Wilford to steal a header past Mark McGeown.
Clyde should have added a second, but a timely intervention by Dunn turned a Simon Mensing header away for a corner. The one way traffic continued and McGeown did will to block a Gilhaney shot. As the keeper lay on the ground, Craig Bryson knocked the rebound over the crossbar.
Gilhaney glanced a header wide of the goal from a Ian Harty cross before Airdrie broke away to equalise. A neat McGroarty back-heel set up Stephen McKeown,and when Bryn Halliwell failed to hold the shot, Kevin Barkey netted the rebound.
Clyde restarted as though they meant business, and with the aid of the wind pinned Airdrie inside their own half. The attempts to create openings were proving difficult.
Clyde came close when Bryson should have done better than shoot over the top from a Mensing cross, and the home side were soon to pay heavily for those missed chances in the first half.
Airdrie gained in confidence as Clyde faded, and when the home defence failed to clear a Barkey corner, Owen Coyle stabbed home the winner from close range which cost Clyde their unbeaten record.
