Like the others I have so many but if I had to chose it would be my solo QXC going into E Mids. Entering the zone and talking on the radio made me feel unbelievable.
The feeling of knowing I was FLYING, and achieving a lifetime dream was amazing. On finals my PA28 became a 767 and as I taxied past all the shiny jets it was great to hear the tower tell a BY757
".....pushback approved after the PA28 has passed behind"
A lovely feeling being in and around the big stuff
