Another neglected beauty (this time from the past):
The McDonnell-Douglas DC-10, in all it's major versions powered by General Electric engines. The DC-10-10 (domestic), DC-10-15 (hot and high) and DC-10-30 (long range).
Pratt&Whitney versions from the -40 series will need more work and time.
And yes, I said
versions. Despite being both P&W Northwest and JAL trijets were fitted with different type of engines.
