Then calculate the odds for me, if you will, of two unattached commercial
airplane/glider instructor pilots, instrument, FAA Safety Counselors (not to
mention both Amateur Radio operators and computer geeks) meeting at Oshkosh,
falling in love, and being married now for 8 years or so, if my math is right?

roughly:
P = (1 - probability of such people successfully mating with anyone else)
* probability of such people bumping into each other

Looks like close to 100% to me.
