Two men:
The parasol wing sat directly above the pilot’s head. During a dive bombing run (the B1A10’s intended role), the wing blocked the pilot’s view of the target. This was a fatal flaw for a dive bomber.
The pilots who tested the B1A10 wrote the first tactical manuals for carrier dive bombing in Japan. They experimented with dive angles, release altitudes (never below 500 meters in the B1A10 due to slow recovery), and formation tactics. These manuals were used to train the pilots who later attacked Pearl Harbor.

If a fresh battery doesn't work, the key fob itself (the transmitter) might be malfunctioning. Check for: Water damage or corrosion on the circuit board.
Loose components (like the transponder chip) if the key has been dropped. 4. The Last Resort: The Module
