My brother and I had a trip to Florida and showed up an hour till closing and the guy at the front said if you wanna see anything go see that exhibit. The show, the walk around and all the cool segments around the ship made it all worth the money. Icing on the cake we went and ate at a restaurant on the water that night and space x was doing a launch and we got to see that while eating to our surprise. Best night of that vacation.

Methane has no smell, that’s why it’s so deadly. I think your thinking of sulfur gas.
