Idle ponderings on aircraft design aside, I just can't stand to sit in a slow aircraft anymore...most aircraft just seem so inefficient...so much induced and parasite drag that could be eliminated, not mention better thrust efficiencies.
Not hard for me to sit there and ponder the wings gong back 40 degrees, the airspeed increases 40 knots, the FMS shows that my trip will be 3 hours instead of 4...that would be so nice.
