The briefcase incident lore:
Monza - 1991
involved: A.Senna & G.Berger
When Ayrton Senna and Gerhard Berger were flying in a helicopter to the Italian GrandPrix, Ayrton had a briefcase with him.
He claimed that the briefcase is indestructible because it’s made out of carbon fibre so Berger decided to test that theory.
When they were flying above the Monza track he literally threw out the briefcase (it had McLaren contract inside) out of the helicopter and watched it fall from the height of about 150m and hit the ground.
Ayrton had no idea that that happened because he was sitting in the front of the helicopter with the pilot and with a headset on (Mr. Important).
But after they landed a marshall came running towards them with Ayrton’s briefcase in hands.
At that moment Senna turned toward Berger and said “You didn’t do it”
