How Much Does A 707 Weigh?

Tue Feb 07, 2006 9:39 am

Another post talks of DC-8's still flying as freighters in the US. The DC-8 always seemed like a heavy duty aircraft, compared to the 707. I would be curious what a 707 weighs, compared to a DC-8. I seem to remember a DC8-71 weighed about 136,000 lbs.; don't know what a std 8 weighed.
Not as easy as originally perceived

If you have never designed an airplane part before, let the real designers do the work!
