The Thunderbird entered production for the 1955 model year as a sporty two-seat convertible. Unlike the Chevrolet Corvette, it was not marketed as a sports car. Ford positioned the Thunderbird as an upscale model and is credited in developing a new market segment, the personal luxury car.
When you have excess air in your stomach, it usually comes out as a burp. Usually the burp will have a smell of the food that you ate, but sometimes it will come out smelling like rotten eggs. This is a condition that is known as sulfur burp, and they can be very embarrassing and unpleasant, especially if they happen in the presence of others.
I have noticed a bad smell, like rotten eggs, in my house that comes and goes over the past 2 or 3 days. Update: I didn't think about this until just now, but the past 4 or 5 days I have been hearing this loud swooshing like noise that is coming from somewhere in my house or maybe the neighbors (I can't tell).
