I had my 4th flying lesson and the ride was so bumpy, I felt like I was on a rollar coaster, no wonder the airport was not so busy today. Yesterday, was a nice day to fly so many airplanes. Sometimes the plane, would go right even thought I didn't move it. I need to work on the bumpy/turbulance fear because it is like hitting a pot hole when driving on the road. I still did the same thing as last time, slow flight, power off stall, I couldn't do power on stall because the clouds were at like 4000 feet and when we fly around 3000 feet it was bumpy. We try to avoid the clouds. I will be flying again next week. It took me about half an hour to do preflight check. On Friday, I went to the San Jose Museum of Art for my friend's work holiday party which we work for the same company. I was not so impressed with the museum, kind of small.
