Eating distracted them a little from our environment . Everything was fine until the plane started to experience a lot of turbulence . My cousins started to get afraid again . Soon , the pilot announced that there was nothing to worry about . A couple minutes later , the plane flew smoothly again . Eight hours later , we arrived at Mexico . We were not only excited to be in Mexico , but we were excited to be on solid ground again . Question: When did they fly the plane? Option1: Last summer. Option2: This summer.
