Bloody hell... Mentour Pilot is an aviation channel that normally never ever do political videos, but they've just devoted an entire episode to hybrid warfare 😲
Apparently Putin has been attempting to deliberately firebomb multiple civilian aircraft in Europe, including cargo and passenger planes: https://www.youtube.com/watch?v=COo5yN6u1Cw
The bombs were sent via cargo services, but cargo services widely use passenger planes to deliver cargo. As the video points out in detail, a fire on board a plane is probably the worst danger a plane can face, worse than engine failure.
