   The huge belly of the IA-33 is clearly seen here ; unusual wing position and landing gear makes it somewhat reminiscent of the experimental rocket and jet German fighters of the end of WWII. lat view 11k

   Here can be (barely) seen the diminutive "T" shaped horizontal surface, a clear inheritance of the TA-183. On the left and lower side of the fuselage is the two leaf, perforated plate brake, in semi-extended position.
In fact, the Nene engine main parts (compressor, combustion chambers) were all "packed" in the first half of the engine length; the rest was a narrow constant diameter tube that extended up to the exhaust nozzle. So, the Pulqui II tail had a lot of empty room, so as to permit the installation of the above mentioned brake. tail 12k

   These two shots show the unusually thin wing roots of this aircraft as well as their "shoulder mount" and strong negative dihedral.

...If you see two big "boomerangs" hanging far behind, they are Horten's tailless gliders. You can see them better at TWITT site
