re: cargo doors
The aft tail (at row 40) is separated and open. Is it true if you can get into one cargo bay, you can get into the others? I also think one side of the airplane can be higher than the other and the cargo bays easily cleared.
re: seats

re: cargo/passenger luggage
Thanks for suggestions, I do have similar items listed on inventory and both technogeeks, chemists and even an engineer from Colt.
