Not a very good picture since it was so far away but it appears to be a 1930s model, a Lockheed electra Model 10. Amelia Earhart was flying one when she disappeared. I could be wrong but that is what it looks like to me.
correction to post 83: This aircraft is NOT an Electra Model 10. The model 10 had twin stabelizers. Sorry about that. DC-1 could be a candidate.
