Diabolo, MNG have cornered the market and do a fine job, they have competition though! the other Turks Kuzu and Orex also operating. Lots of other 40T A310/A300F around on other flags but tied up on contract work. The A300F market emerged well in Europe. However, most operators have their aircraft tied up on contracts and little available for adhoc work, this was once an MNG speciality for adhocs.
