Recalculating....

25,000 MPH=25,000 miles/hr*5280 ft/mile*60 minutes/hour*60 seconds/minute=475,200,000,000 ft./second.

Divide by 3.2808 to get meters/second and the answer is 144,842,721,287 m/second.

Using statute miles instead of nautical miles (6000 ft./mile), which would give a higher result.

I always worry about close calls shaving/disrupting the atmosphere, taking some with it.

Guys, tell me I’m wrong about the minimum approach, 50 miles. I can’t find the margin of error for the approach calculations but YIKES!

“25,000 MPH = 475,200,000,000 ft./second = 144,842,721,287 m/second.”

Sorry, but you’re double dividing, meaning that you’re multiplying when you should be dividing. By your logic if 25,000 MPH is 144,000,000,000 m/second, then 25 MPH would be 144,000,000 m/second (or about a million miles per second, which it clearly is not).

That's way high.

Just google it: 11,176 m/s, or 6.9444444 miles/s.
