Two other military aircraft (though neither saw production):
Boeing YC-14, powered by two GE CF-6 turbofans
McDonnel Douglass YC-15, powered by four PW JT-8Ds
The latter evolved into the C-17; as for the former, one of two prototypes is now a museum relic.
As for commercial operations, I believe the Ilyushin Il-76, another 1970s design (featured in Tritanic's post), is the only one.
The aeroplane has unveiled for us the true face of the earth. -Antoine de Saint-Exupery
