Re: Emirates signs a commitment for 36 additional A380's

Airbus (or any business) won't sell for less than cost, and I doubt cost is that low. Airbus says they are taking a "non-material" lost on the cost of A380 production. In other words, Aibus says they are selling for less than the cost of production, but that the loss is not a big deal amo...

Re: RR Ultrafan vs P&W GTF

GE seems to be all about material science and a hotter core. RR and PW both seem to be into better fans, with gears and maybe variable pitch. Anyone wanna guess what the result of a combination might produce, in terms of fuel consumption compared to current technology.
