In the air now from the volunteer receiver network

None of this operator's aircraft is in the air over the United States right now, as far as the network can hear. See them on the live map. Counted here: aircraft on the certificate and aircraft the company owns. No callsign is on file for this operator, so flights under another code are not counted. Aircraft whose owners asked the FAA not to be displayed are left out.
