The ANT-27 responded differently from the German flying boats, prompting the designer, Andrei Tupolev, to travel from Moscow to observe the unusual behavior firsthand.

[citation needed] Tupolev went ahead in a boat to observe the start of the takeoff closely and monitor the aircraft’s transition to the "step" redan.

As the aircraft began its takeoff, Tupolev noticed the pilots applying the rocking technique.

The impact caused the struts of the central power unit to collapse, and the heavy engine fell onto the cockpit.

[citation needed] The crash resulted in the deaths of KOSOS naval brigade head I. I. Pogossky, engineers G. S. Noskov and K. K. Sinelnikov, and the second pilot, A.

Some indicate it was the deceased Volynsky,[citation needed] while others suggest that T. V. Ryabenko and D. N. Ilyinsky were also on board, piloting the aircraft and surviving the crash.
