Blackbirds are not for public sale. You cannot just go about and fly a SR-71. If you are in the US Air force, then maybe you can be recruited to be the pilot of top secret plans like the SR-71.
OD.
Over drive
The OD button means "Over Drive", off or on.
When the OD (I'm assuming OD = Over Drive) flashed on my 99 Ford Windstar, it was the transmission going out. $2,500 later, it was fixed and never had an OD problem again! Good luck!

Od is over drive . Its only in auto trans. You take it off when you are pulling something.
You can leave the OD ON for general purpose driving and freeway travel. Use the OD OFF function for enhanced torque applications climbing hills or accelerating around tight turns) or seat of the pants driving experience.
Answermost times you drive with od turned off if you are towing in extreme conditions and od is going in and out, also in extreme slippery conditions one might turn od off.AnswerOn a tractor-trailer you get better fuel mileage with your overdrive off--the truck is most efficient in "direct drive," where the engine is connected directly to the differentials. Every gear pair your power goes through costs you power due to heating.
OD stands for Over Drive and it just means that your car is adjusting its actions to save money and gas.
