Me and my brothers decided to build a plane out of our wagon one day 2X4's and wood paneling...looked good enough. grandmother left at 11am everyday in her truck to head to town, so we tied a long rope to her bumper and around the frame of the wagon and waited. she came out and started the truck. we rushed the wagon in place and the middle brother ( he was the lightest of all three) got on the wagon, and we handed him the other end of the rope so he could pull it, and the knot would release the wagon. the road to our house was a long straight road down to the highway and at the end he was supposed to pull the rope and release the wagon. granny took off and we followed on our bikes. the wings were twisting in the wind not rising an inch when she stopped at the intersection and took off again. brother was pulling the rope as hard as he could, but would not release. we lost sight of him on the highway for a bit, until we came around a curve and saw him pulling the wagon coming our way, covered in mud and stick-tights from the ditch he rolled to a stop in. the plastic bearings had melted and were smoking from friction and one of the wheels had lost the rubber tire off the rim. he wasn't injured, so we hurried home and waited until she pulled back up in the driveway....i distracted her while my brother untied the rope and we swore each other to not say a word about the incident.
