I posted about DynCorp 11 days ago. They've been on my "radar" https://voat.co/v/pizzagate/1530442

Here is something really underlooked that I think researchers might find useful https://www.therenditionproject.org.uk/flights/companies/

edit: some additional information about DynCorp

The company is a leading private contractor of the American global police state, a beneficiary of the "war on drugs," the "war on terrorism" and corporate globalization itself. Like Enron and other multinational corporations, DynCorp enjoys a special relationship with the US government leadership, doing "unsavory" work in hot spots around the world. The US government has "plausible deniability" when things go wrong (for instance, when people get killed). DynCorp gets big government contracts.

In addition to its intelligence "database management," DynCorp wages war. It is one of many corporate proprietaries or "cut-outs" that run covert and overt American military operations all over the world. From the support and training of the Kosovo Liberation Army (KLA) terrorists, to firefights alongside right-wing narco traffickers in Latin America, DynCorp has been there.

The outsourcing of US government violence is a time-honored trick. Not covered by the military rules, private mercenaries enjoy the freedom to commit a wide range of US-sanctioned mayhem, alongside the CIA and the Pentagon, while being lavishly funded with US taxpayer money.

DynCorp is the leading corporate mercenary behind the Plan Colombia, or "Andean Initiative." The company has a $600 million contract with the State Department to carry out "defoliation" in Colombia, Bolivia and Peru.

In Colombia, DynCorp works closely with the US-backed and US-funded narco-trafficking right-wing Colombian military, paramilitary death squads, and the CIA.

According to its State Department contract, DynCorp "participates in eradication missions, training, and drug interdiction, but also participates in air transport, reconnaissance, search and rescue, airborne medical evacuation, ferrying equipment and personnel from one country to another, as well as aircraft maintenance." DynCorp operates State Department aircraft, including jets, helicopters and crop dusters and provides all the personnel required to conduct warfare in Colombia, including administrative personnel.
