- Aircraft run their engines at or near redline all the time. Piston engines
- are designed for fairly low revs (2500-2800) and just run there for
- about 1500-2000 hours which is about 250,000 miles. Airline (turbine)
- engines run about 3000-4000 hours which works out to 1.5 MILLION
- miles at 3500x 350-400 mph..

- If they said 100K miles, then I'd assume they drove a car - but not in
- top gear, since most engines won't pull redline in top gear. Still
- it would probably be at 100+ mph, so it's a 1000 or so hour run.
