I know it's all just fantasy and the driving force behind the entire thing is making money but sometimes I wonder just what the people making this stuff up are on.
A 47 foot long, 20 foot tall, eight legged, armored transport with seats for 34 fully loaded out for combat troops, that's made out of some sort of magnetic material weighs less than 40 tons? And a carrier designed solely for the purpose of carrying heavily armored transports into combat can only lift 40 tons?
We've got Helicopters capable of picking up over 20 tons of payload and we don't have the benefit of repulsorlifts. The record for a Helicopter is over 44 tons of payload. I won't even get into fixed wing aircraft.
Oh well, in my little corner of that fantasy galaxy the LAAT/c is capable of lifting an AT-AT and I try my best to ignore a lot of the technical discrepancies.
Anyway, back on topic...
Here is a video LAAT/c carrying an AT-AT, proving it is possible. http://www.youtube.com/watch?v=b3IOpmGex1g
