Flying the Magical Hatz Biplane 

Something to keep the 4 strut wires from vibrating so much probably. Also people put similar rods out there like that as a reference point for acrobatics when they look out the side.

ok thanks

They are called javelins......they stop harmonic vibrations in the flying wires.

Light general aviation aircraft like the Hatz biplane operate below 12K feet where oxygen is not required. All pilots wear seatbelts. In open cockpit aircraft there is still a possibility of being aerodynamically removed from the cockpit unless you are strapped in with your seatbelt. Perhaps from turbulence or other unusual attitude.

oh ok thanks for explaining

Commercial airlines also have pressurized cabins. Which is why the windows don’t roll down

Billy Williams s

NORDO (no radio). At the time of the video the aircraft operated in non-towered environment.

Basically, the airplane is balancing on the wing. The heavy engine is to the front. The pilot in the back balances it out. The plane could be designed to balance with the pilot in the front, close to the wing. But if that were the case, whenever he took up a passenger, the plane would be tail heavy, which is a very unsafe situation. So they design the plane to balance with the pilot in back. The passenger is near the wing and doesn't impact the balance as much.

@@davidcash7543 Thank you so much for the reply! That makes perfect sense. I've seen the same situation with Boeing Stearman's , where the pilot was in the aft cockpit, and I always wondered about that. Thank you for clearing that up for me! Best regards, JA

David Cash - As a pilot I want to comment on how clear and precise your explanation was. Well done! 👏
