What a ride. I wonder how far she would have skidded if the chute hadn't opened. Amazing that there was no fire.

I think that ride needs some winglets to keep her stable at those speeds.  |

Absolutely amazing! Safety equipment and crash-resistant vehicle design really paid off big!
This SHOULD (but probably won't) be a wakeup-call lesson for riders and ESPECIALLY car drivers with vehicles that can approach and surpass 200-mph. That includes some "crotch-rockets" and a few new cars from Dodge, and foreign makers.
Everything can be just fine, and in an instant the vehicle can go airborne. After that, it is totally out of control and the landing won't be pretty.
We've seen NASCAR cars do this and they are designed for such speeds. I don't know at what speed this phenomenon is likely to take place, but I suspect it's anywhere after 140 to 150-mph. IF you get a little air underneath, OR if your vehicle body-style generates a little lift, once you hit the right speed, you WILL become an airplane... Piston Guy's suggestion to include air-stabilization of some kind is a good idea on these mega-fast vehicles.
When I was young, such speeds with street-driven bikes was almost unheard of, and never seen in cars. Today, several factory-made vehicles and numerous hot-rods ARE capable of such speeds, and riders/drivers need to watch out. These rides can go fast enough to fly. Literally!
Ride safe, and keep yer' wheels on the ground!

Yes yes yes. the Aero package is a big deal once we get over 100mph.. My late model CBR has some patent pending bodywork on it to keep the front end planted at speeds of 140mph+. If you have ever ridden two wheels in the area of 150+mph you will notice on a inline four the front end starts to get very light, conventional bodywork with a inline four starts to become a barn door and provides Lift. Honda designed the bodywork in the wind tunnel and there is all kinds of venting for the air you are now pushing. With ignition and the pipe she a solid 186mph ride and that is very serious business when your arse is hanging out in the wind,I take it very seriously it takes awhile to get there and a while to get her wowed down.. Not a very good pic but you can see the black lip and the venting in the front fender.  |

winglets don't do much for for the craft equipped with them
other than a small boost to lift at the wing tips
the primary purpose is the reduction of the vortex
that allows for the aircraft behind to land sooner safely
I think a land speed motorcycle would not welcome extra lift

Anything that will provide downforce will slow the vehicle down, Im sure there trying to find some happy medium. |

Here is a Moto GP bike with Winglets to provide downforce, they call them winglets and not sure if that is technically correct The sanctioning body banned them.  |
