Millet Fanger is correct. One insurer for $100K to $1 Million (in the case of the A380) and a group of insurers for amounts above that. First $100K is the Qantas excess.
A lot of misinformation on this thread.
MF, I think I went to Tech with you back in the early eighties. A little known aircraft called a "Millet Fangar" that would be periodically discussed?
