> 7 min/mile, or 100 m in 25 seconds seems doable if you excercise regularly ...

I have to disagree. I run 20 miles per week at about 11 min/mile yet could not run a single 7-minute mile to save my life. The best I can do at a "max effort" is a single 9-minute mile. Never even a 100-yard stretch in the 8s.

But then, I'm 77 years old.

Nowhere in this discussion have I seen an accounting for age. Perhaps with advancing age walking is more efficient (whatever the metric) regardless. Anecdotally (I see that word used here a lot <g>) I don't see any other runners my age, only walkers, so that must be true.

> I wonder how often the missile is in alert status?

In 1972-74 when I was a Minuteman I launch officer (DMCCC) our 10 missiles were /always/ on alert. You would expect to see 10 green "Strategic Alert" lights across the crew commander's (MCCC's) console unless something was wrong (requiring maintenance or a brief calibration).

IIRC we were in a perpetual state of DEFCON 4 in those days.

Not true -- I currently access the API to obtain an aggregated feed in exchange for my feeding ADSB-X with my receivers (1090 and 978 MHz). You have to ask for access and it's poorly documented but it works and feeds my own local tracking site running 24.7.

Wait. Uppercase wasn't used for the personal pronoun "I" or to begin sentences in web0?

Not cool.

And not even a ReadMe file to accompany either ZIP file.

This is not true. ADS-B OUT is required to fly in certain classes of airspace, above 10,000 feet, etc. -- anywhere a transponder is currently required. That's all.

That leaves a lot of airspace in the US. Someone flying his C182 in eastern Wyoming may not bother with it as he does not see any benefit. Here in western Oregon, I see the benefit (weather and traffic via ADS-B IN) and have equipped my aircraft even though I (mostly) avoid the airspace where it is required.
