Finding Family 5
As soon as both boys were up the next day, the prepared to try out the glider. Mark was finishing the wings of the second glider, and John was running around the rock trying to decide where he would glide to if he was able to take off.
"hey mark!" he called. "Do you think I could glide to the lake, or should I just try to make it to that rock?" john guestured at a boulder about 30 feet away from the launch site.
Mark looked at where John was pointing, then said, "I bet you could get to the lake. Just make sure that you don't go too far into the water. I don't want the glider to get ripped!"
When they were both ready to try the gliders, they climbed up to the top of the rock and looked down.
"it sure looks a lot taller from up here" mark remarked. "you sure you still want to do this?"
"sure I'm sure!" and with that, John hopped off the side of the rock and began to glide. He sunk a little at first, but then he rose up as soon as he emerged from the downdraft caused by the wind blowing against the rock.
"hey mark! This is really fun! I'm going to try to make it to the island!"
Mark tried to call John back, but John had already started across the lake. The glider shuddered a little as it passed above the cold water of the lake, but John easily glided to the island. As soon as he landed, John realized a problem. "Hey mark!" John called to his broher, who was now standing on the shore of the lake. "how am i supposed to get back!"
Mark immediately called back, "just stay there! I'll try to build a raft to get you with!"
