I like this picture, but most of all it shows E3B-369 in the background.
Nicholas Montesinos - Grenada 1964
“Elementary School of Pilots, B.A de Armilla (Granada).
The author (in uniform) with three classmates, in one of the School's two hangars.
The Bücker (E-3B) was used to make; circuits, spirals, slides, augers, formations, and acrobatics.
The I-115 (E-9), to make very basic instruments (it was not equipped for that function), the rear cabin was painted white, and a dash was placed between it and the front one.
The reality was that the E-9 for this purpose did not work and was never used again.“

E3B-369 is now G-BPDM in England



These are the only three pictures I can find. Anyone have any recent ones?
