  1. 700 feet AGL
  2. 1,200 feet AGL ✔
  3. 18,000 feet MSL

Why: The FAA handbook says the Class E base is 1,200 feet AGL in most areas. Near many airports it drops to 700 feet AGL or to the surface. Below Class E is uncontrolled Class G airspace.

Huh, didn't know that: All airspace above FL 600 is also Class E airspace.

What starts with E, ends with E, and has only one letter in it? An envelope.
