the Lufthansa heist________1978__________a Mafiosa operation______________one of the biggest heists in U.S. history

from Wiki:

"The Lufthansa heist was a robbery which took place at New York City's John F. Kennedy International Airport on December 11, 1978. An estimated US$ 5.875 million (equivalent to US$ 27.6 million in 2023) was stolen, with $5 million in cash and $875,000 in jewelry, making it the largest cash robbery committed on American soil at the time.

The money and jewelery have never been recovered."

at least 11 thugs and maybe as many as 20 who were either associated with the crime or knew details about it were murdered after it happened

most probably to keep them from squealing about what they knew and/or so as not to have to pay them their fair share

Louis Werner, a Lufthansa cargo worker, was the only person ever convicted and jailed for the robbery
