The UK used to run the flights themselves with their own military spy planes. They argued that this would strictly be for hostage rescue. Given that they spent hours circling Gaza daily and live-streaming any and all information to the Israelis for almost two years, a time in which not even a hand full of hostages were recovered by military means, that seems a big lie.
Now as the UK feels pressured to stop their direct involvement, they are instead paying American private contractors with UK taxpayer money, to do the dirty work for them. We now have the evidence as those were too stupid to turn their transponders off. Before that Matt Kennard could only verify multiple spy planes taking off and landing from and towards Gaza at the UK army base in Cyprus daily. But they turned off their transponders once they came close to the coast of Palestine.

UK is running spy flights for Israel, or now contracting them out to US mercenaries, to help Israel turn Gaza into rubble and mass slaughter Civilians. The UK claimed it would be solely for hostage rescue, but there was hardly any hostages recovered by military means and certainly no daily attempts at rescuing hostages, but Britain provided intel daily for the past almost two years.
The UK government said they stopped their flights amid mounting pressure, but that was just a lie as they contracted it out instead to distance themselves, which also indicates that they know exactly which crimes they have been and are supporting.
