Jagdstaffel 11 was the Red Baron's squadron. It seems some folks have built reproductions of the Fokker Dr. 1 Triplane and they've tricked them out in the pain schemes of each of the Jagdstaffel pilots. Cool.
It's amazing just how short a field those old birds need to get airborne - less than 100 yards, and maybe no more than 50. It's also amazing just how slow the fly bys are - I'd think no faster than 80 MPH. The top speed was only 115 MPH, and you wouldn't stall until your speed dropped to 45 (!) MPH - maybe the lowest stall speed of any fighter, ever.
