In turbulence, there is a difference! What one type will report as light chop, another will call moderate. Of the four jet types I have flown, the L-1011-500 is the hands down winner.Handling is great too.
Active controls (ACS) and direct lift control (DLC) make both cruise and approach turbulence much less uncomfortable.
The second best handling ( but not riding) aircraft I flew was also a Lockheed, the L-188.
Good on yer, skunkworks, when are you going to build a viable SST?
