Going down Star Wars Canyon in El Centro as a midshipman in the backseat of an F-14. All the fun of flying jets and none of the work.
Leading my form partner and instructor into the break in Primary, looking back and seeing two more T-34s tucked tight in parade under my wing. Doing my second-to-last Primary cruise form hop as wing, going into a tail chase barrel roll and watching the world literally revolving around me.
Taking a picture of me and my folks in front of a T-45 during my Advanced RI cross-country and watching it spead like e-mail wildfire to all of our relatives and distant acquaintances. Our son, the jet stud. Realizing how damn proud they are.
Spending 5 days on the road during my Primary cross country. Two memories in particular. Doing a VNAV from NAS Jax to NAS Atlanta and watching the sun set as I took off. Fun watching the rest of the world turn in and the day end from 2000 feet, and playing the "I wonder what life is like in [fill in the town I'm flying over]" game. Picked up IFR to shoot approaches into NAS Atlanta, and my instructor took the controls shortly thereafter. Peeked outside the cockpit to find myself almost right over downtown Atlanta at 3000 feet, with the city and the skyscrapers lit up like Christmas morning.
Two days later, VNAVing from Lakeland down over the Everglades and then almost the full length of the Florida Keys at dusk. Landed totally beat after shooting probably 15 approaches that day, and then opened the canopy to have a warm ocean breeze carry the smell of salt spray and mangroves into my cockpit. Welcome to God's Country. Randomly running into two other studs I knew on Duval Street whom I had no clue were down there.
