That's because jornos are general and not specific. They kept saying they had spoken to pilots, but had they listened; had they delved deeper with the pilot and taken notes? They asked easy general questions that could be swatted and they didn't have the knowledge to follow up. Steve Sacker did the same on Hardtalk. The researchers must have been very wet behind the ears.
MOL challenged the jornos and the pilots to present facts, not anonymous puppets claiming to be RYR pilots. He claimed everything was a lie. He said he would give a guarantee of no recrimination to any pilot wishing to raise issues. Why does RPG not accept the challenge and have a public debate with MOL. I'm sure CH 4 would oblige. They have a very public guarantee that nothing will happen to them. He would be under the spotlight if there were any recriminations.
