SAS Galley Cart: Ready for service
This is a 1970s-vintage galley cart from SAS airlines; when I found it at an aircraft scrapyard, it looked like this.
I cleaned it up at a self-serve car wash, then built some interior shelves out of acrylic plastic. The cart opens on both sides; this side holds the booze, mixers, and bags of pretzels; the back side holds glasses and barware. When not in use, everything stows neatly inside.
Needless to say, next time you see someone scooping up piles of napkins and bags of peanuts during your next flight, it may be me, trying to re-stock my cart. Flight attendants are usually pretty indulgent when I explain that I use a galley cart as a bar in my living room.
