RE: 1st Solo, and some trees!
Not the end of the world....get another plane!
Don't feel bad. Back in my early days.....I didn't encounter any trees. What I did encounter wasa good, high altitude, a nicely trimmed plane on a calm day, 3/4 tank of gas, having a great time.....followed by a "loss of control." Meaning I watched my plane keep going. And going. And going. Never to be seen, or heard from again.
For all I know that plane is up in orbit somewhere.
