Basically to get unlimited fatigue life with aluminum parts you need to keep the cyclic loading below 5% of ultimate.

So all the aluminum will eventually need to be replaced.

I don't know what the 'safe life' or a B52 is, but they estimate a number of hours/cycles for crack growth to begin and base maximums around that.

The air force does damage tolerance analysis too (for life after crack formation), but I think that started after the b52 program (and i cant remember details offhand)

Not financial advice:

Any lender can give you an FHA loan, it gives you rates comparable to a credit score around 750 (so little to no benefit for the top 50% credit percentile). They allow you to put only like 5% down but I believe there is a mortgage insurance fee of like 3% of the purchase price upfront

When you do get a mortgage look at zillow and bankrate to find competitive lenders and reach put to 7 or 8 of them so you can get your interest rate down
