Absolutely.

The only delta-wing aircraft I approve of.  :wiggle:

I remember getting a plastic model of the B-58 Hustler by sending in box tops from some cereal and 50 cents handling.

That model held a hallowed place o my book shelves for years.

Tous, answer a question for me. settle a discussion

aircraft engines (and assorted systems) are tracked by hours operated.

but the airframe is tracked, mostly, by cycles of take offs and landings. Pressurizing at equalizing. As a means to track and foresee fatigue due to expansion.

check yes or no

or kind of, or maybe,

or sometimes under certain conditions related to use and environment

A couple years ago, our son and I took a ride on a B17.   There are no creature comforts on this plane, and there is a minimum of space.

Awesome experience!

I took a flight on Nine O Nine a few years ago. Stuck my head out the escape hatch also. It was an unforgettable experience.

Good question, amigo.

Let's consider what goes into the design of an aircraft.

The primary thing is, what's it supposed to do?  So, we start with its role and then we can project what sorts of stresses and environment it will be subject to.

Launch and recovery cycles and pressurize/depressurize cycles stress the air frame, but, we have tons and tons of data, both from testing and real world experience we can look at and see what has worked in the past.  This is one case of: if it ain't broke, don't fix it.  Use the best practices gleaned from other people's mistakes.  No need to spend 10 million dollars for an outside the box solution to a problem that has already been pretty much solved.  The same with launch/recovery cycles.  We know what happens when an aircraft leaves the ground and then returns and again, we have years and years of data on what works and what doesn't.

 

We also have tons of data on what works with carrier-based aircraft, how many launches and how many traps before a light inspection, how many before a complete inspection, how many before we need to replace parts.  We're also well aware of the effects of the salt water environment and what it does to pieces.

 

Aloha Air 243 was an anomaly and was judged to be due to poor maintenance, not poor construction or design.

 

Note that the designers of the Airbus A-380 departed from the basic cylindrical fuselage for an oblate construct, so they had to get their slide rules out and do some work and a lot of modeling and testing.  They'll know if they got it right after years and years of the aircraft being in service and many inspections.

 

Engine manufacturers give us extensive details on every single piece of their product, how often a bit must be inspected, how to inspect it, how many hours before replace or refurbish.  They also have the same years and years of experience and tons of data on what works, what doesn't. The same with every other part that we source from outside.

 

When we deliver an aircraft to the Navy, we don't just hand them the keys.  We supplied recommended inspection cycles, recommended maintenance intervals and procedures, test procedures and test rigs and training on how to do it all; everything  they need to keep the aircraft safely in the air.

 

If the recommended maintenance and replacement procedures are followed, air frames should last for 100 years.

That was the plane we were on.

It was not as loud as I thought it would be.  And it felt very 'solid' in the air.  But, it was a calm, perfect day for being in the air!

Unforgettable.
