[ N58HX Flightaware ]
What are the odds N58HX would show up on Flightaware on a Sunday afternoon while we're talking about it???
Seems of the fleet, this is the only one that isn't blocked. Many times with corporate jet charter services, they don't own all their airplanes. They just manage them, when not in use by the owner, they put the aircraft to work, which helps pay for the airplane.
I live in Toronto, near me is a small airport Buttonville, which has a corporate company Flightexec. They have 3 Falcon 10's, a Falcon 900, and two Citation XL's. The two Citations are owned by separate companies, one is blocked, the other isn't.
As for finding info, sites such as [ AirNet ]
list 25000 aviation sites. Another site [ airlinerlist ]
have production lists, such as every Citation ever produced, and [ Professional Pilot Rumour Network ]
is a site to seek info.
Many times if you find a little info on your subject, you can google it, which leads too?, by the time you find what your looking for, 10 clicks later, you have no idea what site your even on?
I used to work for two corporate jet companies at Toronto Intl (now Pearson Airport), as well as being an avid biz jet 'spotter', I traded 35mm slides of corporate jets worldwide. Many of the 'enthusiast' are still around, and with the internet, most info is just afew clicks away.
