Is it my imagination, but every time we fly into the Nevada city, I can feel my seat jump around. Does the pilot do it intentionally? FLN, Burbank CA

A: Maybe it’s a heavenly warning to be careful of how you bet at the casinos and enjoy the Sin City night life. Seriously, especially in summer, the shaking is because of heavy thermal heating of air surrounding the airport. The nearby mountains and hot wind currents often shake the aircraft as it approaches the field for the landing.
