So, 43,000 hours over 17 years equals 6.9 hours per day, every day for 17 years non stop. No vacation, no training, no sick days, no days off whatsoever.
Well how about this, do the math, for 9 years our crews got 18 flight hours for every 30 hours of clock time for 9 years.... and yes we did didn't get any days off, I took 2 weeks in 9 years when my Dad Died.
As far as the master chiefs having over 90,000 hours of patrol time that's a stretch also.
In todays world you may be right, but during the hotest days of the cold war, it was pretty common flying dew line patrol.
If you take an average 20 year career that's 4,500 hours per year, or 12.3 hours a day every day for 365 days a year. Even stretch that out again to a 25 year career and you're still talking almost 10 hours per day for 365 days per year. Even if the Master Chief went for a 30 year career he wouldn't fly all of that, maybe 25 out of 30. Your numbers simply don't add up.
I was in the Navy also and I never knew of any crewmember to acquire those amounts of flight hours.
