"Landmark Aviation was alleged to have been the FBO of choice for the CIA's extraordinary rendition program, known as the “torture taxi.” Under that program, people were kidnapped, flown to black sites around the globe and tortured for months or years. European governments were aware of this program and some even issued arrest warrants for CIA officers involved.
An FBO is a sort of private air terminal, fueling and maintenance facility for charter, business and private aircraft. Some FBOs are very bare bones. Landmark's Columbus FBO is a posh facility with showers, conference rooms, a dedicated concierge and even its own Customs Inspection.
Epstein's phone book listed Lane Aviation as the sole FBO in Columbus. It is not known if he still uses it, but Landmark's facility does have more posh amenities fit for billionaires, princes, presidents and spies.
The allegations being leveled against Epstein include trafficking minors for sex across international boundaries. The logistics of getting a minor across a border for such purposes would be much less complicated with the help of a Customs facility located in a friendly private facility operated by a company familiar with covert operations and making people disappear. Epstein is clearly no stranger to navigating that social space. Landmark even offers valet parking for the armored Mercedes." Quote from following website:
