First helos and now AvGas and Airstairs
hmmmm, you part of bin ladin's group
I would imagine to power cessna you could use some crude gazoline

Avgas has higher octane levels, and its PPM (particle's per million) is far lower than car gas, making it a cleaner but much more powerfull fuel then
regular fuel, JetA1 fuel, powers jets, turbine props and helos, + the new diesel aircraft, is basicly kerosene
I was just wondering, apart from airport ground, what other places have aircraft grade fuel?

car racetracks, performace shops, etc..., you can tell when a car is burning Avgas, cause it smells funny and makes your eyes water and feel like they
are burning
Also in the airports, they either keep it underground or in tankers right?

at small airports in tanker trucks, you call the tower and request fuel, the truck comes to your plane and fills you up, at the big airports its
underground, they don't build a big enough truck that can haul the amount of fuel a jumbo jet can hold. A 747-400 can hold over 57000 gallons of
fuel
Airports stair tracks, do you need a key to star the ignition or do you just hop in, push a button and of you went? Is there a security or protection
of some sort?

the ones built on the back of pickup trucks need keys, the ones built on the back of a "MULE" is pushbutton, A Mule is the square boxy looking
truck, that you see towing jets around the airport
What are you planing to do Freeman?, or do you just have an interest in aviation?
