No glider bomb there! The a/c pictured is a training glider, used to
train glider pilots. Several types of training gliders were improvised
from light planes, where the engine was removed and a seat/controls
substituted.

The plane pictured is not a Cub or Aeronca or T-craft -- maybe a
Commonwealth?
