Not sure why you're quite so sceptical given Tom Enders well-documented record, but for the record he has 1,000+ jumps of all kinds and is a former German Army paratrooper and subsequently reservist.
The press release should have been better drafted then. Even if he is a former para, I am surprised that he thinks that one jump with a sport parachute off the back ramp on a sunny day at 6000' is enough to pass such sweeping praise on the A400 as a para-dropping aircraft.
