I love the idea that an approximation, cannot be considered correct. As such I am flying because I used the incorrect maths to park my bum in this chair.

You are simultaneously not flying, because the incorrect maths you used to park your butt in the chair are incapable of determining whether or not you are airborne.
I am the Infantry. I am my country’s strength in war, her deterrent in peace. I am the heart of the fight… wherever, whenever. I carry America’s faith and honor against her enemies. I am the Queen of Battle. I am what my country expects me to be, the best trained Soldier in the world. In the race for victory, I am swift, determined, and courageous, armed with a fierce will to win. Never will I fail my country’s trust. Always I fight on…through the foe, to the objective, to triumph overall. If necessary, I will fight to my death. By my steadfast courage, I have won more than 200 years of freedom. I yield not to weakness, to hunger, to cowardice, to fatigue, to superior odds, For I am mentally tough, physically strong, and morally straight. I forsake not, my country, my mission, my comrades, my sacred duty. I am relentless. I am always there, now and forever. I AM THE INFANTRY! FOLLOW ME!
Bollocks, oh yes, and I was enjoying that. Where am I now?
That's just the way physics is I'm afraid! If we didn't know about Newtonian Mechanics we'd use General Relativity to get to the Moon and Mars. If we didn't know about General or Special Relativity then we wouldn't have GPS.
You use the tools to do the job. The mileometer in a car is not made to measure microns. But that does not mean when working out the mileage of the car it is incorrect.

I'd call that a pretty big failure rate, especially when you consider the cost involved in sending probes to mars. Consider also that the average distance from Earth to Mars is about 225 million kilometres, or 139,808,518 miles and some change. This distance varies between 54.6 and 401 million kilometres respectively, which works out to about 33,926,867 to 249,169,848 miles. That's a huge volume of space. NASA aren't so stupid as to send their probes zooming off any old how, hoping that by chance alone at least one of them will actually get there, so they select their launch windows very carefully such that the distance that has to be covered, plus the projected position and movements of the target planet (it would be the height of bad manners for the planet not to be there when the probe arrives), allows for the most energy-efficient transfer orbits. Given suitably inexpensive and efficient energy generation it may be possible to eschew transfer orbits in favour of direct flight, à la Star Trek, but for now we're stuck with them. These transfer orbits are necessarily slower than direct travel could ever be, taking around six Earth months as opposed to thirty-nine days according to one projection. So that's six months of being exposed to cosmic rays, dust particles, micrometeroids, Solar winds, etc. Add to which the spacecraft are designed to be as lightweight and compact as the mission profiles allow, again in the interests of economy in fuel not to mention costs, plus the fact that relativity constrains the telemetry connection between spacecraft and Mission Control, meaning that the probe has to rely on its own artificial intelligence combined with preset landing procedures, plus the fact that the landing sites don't come furnished with runways and landing lights, and that fifty percent success rate, arguable anyway, is starting to look pretty good. You try parking your car, by remote control, with a time delay of several minutes, and we'll measure your success rate. Orbital mechanics - it's not rocket surgery.
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'
Good point. Coming in on a wing and a prayer is fine, but you're not going anywhere without the wing.
