In remote areas, Glass G may go up to (but not including) 14,500' MSL. In most places, G Airspace starts at the surface and goes up 700' AGL or 1200' AGL where Class E starts.

Class E airspace rarely goes all the way to the surface, and in non-mountainous terrain, the floor of Class E airspace is typically 700 feet or 1,200 feet AGL.
Class G airspace is the only uncontrolled airspace out there in the United States. Thus, both IFR and VFR traffic is also uncontrolled here. To find out Class G airspace, note that it exists where the other five airspace classes, i.e., Class A, B, C, D, or E, don't.
Class G. In class G airspace, aircraft may fly when and where they like, subject to a set of simple rules. Although there is no legal requirement to do so, many pilots notify Air Traffic Control of their presence and intentions and pilots take full responsibility for their own safety, although they can ask for help.
Class C or D airspace (at or below 2,500 feet agl within 4 nm of the primary airport) — 200 kias (unless a higher speed is specifically approved by ATC) Class E or G airport traffic pattern — 200 kias (recommended)
CBO operations and events occurring at 400 feet AGL and below in Class G airspace do not require FAA review, approval or authorization. CBO's intending to conduct events in Class G airspace that may exceed 400 feet AGL must contact the FAA for further information.
Transponders Needed for Class G AirspaceFor the most part, pilots flying in Class Golf airspace do not need a Mode C transponder, ADS-B Out function, or even specific communication equipment. One of the few exceptions is that a Mode C transponder and ADS-B Out are required if flying above 10,000 feet MSL.
There is no international agreement on the vertical extent of sovereign airspace, with suggestions ranging from about 30 km (19 mi)—the extent of the highest aircraft and balloons—to about 160 km (100 mi)—approximately the lowest extent of short-term stable orbits.
Class F. Class F is not used in the United States. In Canada, Class F is the equivalent of U.S. special use airspace including restricted and alert areas, while ICAO defines it as a hybrid of Class E and Class G, in which ATC separation guidance is available but not required for IFR operation.
Paramotors can be flown in uncontrolled airspace (Class G and most Class E airspace) and cannot be flown over congested areas of people or restricted areas. Additional areas may be off-limits in the event of a Temporary Flight Restriction (TFR) as noted in a Notice to Airmen (NOTAM).
