Narrative:
On taxi out at runway 35 mht another aircraft was departing prior to us. When we were cleared for takeoff the prior departing aircraft reported a windshear alert and a +/-20 to 25 KTS at V1 or vr? I canceled our takeoff clearance and taxied clear of the runway. Our power never went past idle thrust. Another aircraft departed prior to us and reported a windshear alert with no gain or loss in airspeed. After that report we waited some time and departed with no windshear alert on airspeed gain or loss.

Title: ACR MLG DELAYS TKOF AS RESULT OF PIREP OF WINDSHEAR BY DEPARTING ACFT AT MHT.
Narrative: ON TAXI OUT AT RWY 35 MHT ANOTHER ACFT WAS DEPARTING PRIOR TO US. WHEN WE WERE CLRED FOR TKOF THE PRIOR DEPARTING ACFT RPTED A WINDSHEAR ALERT AND A +/-20 TO 25 KTS AT V1 OR VR? I CANCELED OUR TKOF CLRNC AND TAXIED CLR OF THE RWY. OUR PWR NEVER WENT PAST IDLE THRUST. ANOTHER ACFT DEPARTED PRIOR TO US AND RPTED A WINDSHEAR ALERT WITH NO GAIN OR LOSS IN AIRSPD. AFTER THAT RPT WE WAITED SOME TIME AND DEPARTED WITH NO WINDSHEAR ALERT ON AIRSPD GAIN OR LOSS.
