No one is suggesting that these are certification or qualification tests.
The press release seemed to!
“It was an enormous pleasure for me to experience the excellent qualities of the A400M for paratroop operations. Paratroopers serving with our customer nations can be confident that the A400M will provide a far superior platform for their operations in future.”
Making such confident conclusions on the basis of a very superficial test does not give much credibility to other A400 press releases, which is why I thought it was a poor press release.
