As I understand it, the Fokkeer DR I (Triplane) Had a nasty little habit in that the top wing had a tendency to peel off in high speed dives. The DVII was a far superior aircraft according to a couple of old German pilots Dad knew back in the sixties.
   Phot: I was an aircraft engine mechanic in the US Navy. It was a hell of a lot of fun and I still could handle my own witih a hammer and a screwdriver if push came to shove. Have a great night all, Neil
