Yes, in 1999 Mercedes-Benz built a flying car for Le Mans. Well, in all honesty I don’t think they specifically made a wingless airplane, but that CLR took flight. Despite the horrific (and absurd) crash, Peter Dumbreck walked away unscathed, a proof of Mercedes ruggedness. Though maybe they should consider a built-in parachute.
PS: That was the second CLR to reach for the clouds at La Sarthe. During practice on the Friday of the race Mark Weber flipped car #4 🛫.
