I use to work at the Tucson Intl Airport a few years ago and one of the airlines was shooting a commercial. They had offered for TIA employess to fly in the plane as they were filming. They said we would be flying up to and over the Grand Canyon and back in an hour. I jumped on the chance because I do like flying after the take off and before the landing. LOL Well, after we all were on board the plane takes off. We circle around the south of Tucson, headed north to the canyon and then circled around back to the landing strip. The plane touched down on to the strip and instantly jetted back up into the air. This continued for about an hour !! An hour of Hell ! We never made it to the canyon needless to say.
