Why stop at the S61? How about the Comet? Lockheed Electra? Chronic B29 engine fires. One of my favorites was the Nieuport 28 shedding wing fabric until it was discovered that moving the stiching back 6" solved the problem. Today we have 737's that have rudder hardovers and Airbuses that have tails fall off from a little turbulence. Heck the Boeing 787 has design problems and there hasn't been one test flight yet. Point being - as long as man is building stuff, things are going to go wrong - all you can do is the best job possible, don't be affraid to point out problems, and for those of us that fly, use common sense along with the checklist.
