This is my 1.5:1 Boeing 737-900ER in Delta Air Lines livery and the interior is done in their seating layout. The aircraft even has "fuel" in it (water) in the center tank. The aircraft also has "black boxes" (orange wool in the tail section) data recorders. I tried to put the orange life raft/slides under the doors. I created some ground equipment like air stairs, baggage trailers, fuel pump, a catering truck, and a baggage loading vehicle. The leading edges of the wings has slats and the trailing edge has flaps(w/ Fowler flap trailing edge guides), spoilers/inboard ailerons, and ailerons(outboard). The horizontal stabilizer has elevators as well.
