The IA-33 PULQUI II

In the case of Kurt Tank, he was offered a position with the British, but at that times the English aeronautical industry didn't offer a good future for him; he was also contacted by US representatives, but Tank hated the North-Americans. So, the logical option was the URSS.

Tank was kept as a "prisoner" in the Schaumburg castle in the British zone, but had the freedom to go and return almost without restrictions.

He began conversations with some Soviet agents in the occupied Berlin, taking with him, drawings and calculations. It is supposed that he took with him the plans of the Ta-183 I and II (that had been prepared for an emergency program of jet fighters for the Luftwaffe, in mid 1944), and perhaps his 'idea for a jet fighter that could be powered by a Rolls Royce Nene engine'. The representatives that the URSS sent to that meetings were very kind, and had deep knowledge in the aeronautic subject, so Kurt Tank began to feel comfortable, thinking he had a good future among them.

But on one meeting with them, a Sovietic general (who later passed to the West) told him that he was not going to be allowed to return to the British zone, and was going to be taken to Moscow. With his help he escaped, abandoning all the documentation in Berlin.
