Interesting. I'm just reading a book now which talks about the bribery-fest between all the major US manufacturers when they were all trying to backstab each other (remember the ANA Tristar/DC10 deal?) and keep Airbus out of the market.
It says that in 1982 Boeing finally admitted, after years of denials, to withholding information on payments to foreign officials and pleaded guilty to paying irregular commissions to agents - mainly to Spain and Lebanon but also to individuals in Honduras and the Dominican Republic.
