Data from various arbitrary public sources would be difficult to put into a rational schema. Querying that schema would also be more difficult that a full tact text ES query

This website does a great job explaining how encryption works and how it's vulnerable to bad RNGs. Well done.

I wonder what would happen if they flew for more than 90 days putting them in violation FAR 61.57

> (1) Except as provided in paragraph (e) of this section, no person may act as a pilot in command of an aircraft carrying passengers or of an aircraft certificated for more than one pilot flight crewmember unless that person has made at least three takeoffs and three landings within the preceding 90 days

This was in 1958. FAR 61.57 was first created in 1999.

Even then, it'd probably be fine if the passenger was (for example) a flight instructor.
