Jason,
Probably for the same reason that the few all electric sport airplanes use them, higher energy density. Their battery packages are 25% lighter than what I could assemble using LiFePO4 cells. I'll gladly pay that weight penalty (well since it is an aircraft, to keep useful load then the same weight and less capacity) for both a safer cell and costing much less.

It was most likely someone selecting the battery chemistry according to a list of lithium chemistries, sorted by specific power, and not considering safety and failure modes.

Not all Lithium's are created equal, I would never put Lithium Ion in a boat or plane. LiFePo yes. Does anyone here understand why Boeing decided to use Lithium ion?
for all you lithium guys I have one word "DREAMLINER"
if Boeing with their resources could not make it work,what do you know that they don't? All dreamliners have been retrofitted to Ni-MH
