Well I almost flew an Mu2.....in a previous life I was tasked with finding a tprop to move up to...at that time I figured the boss was on a limited budget...so I looked at every $300k turboprop I could find...the MU2 kept coming up as an option...they didn't fly very high, but a solitaire will do 300kt...and they had the highest accident rate for PILOT ERROR, but the lowest accident rate for MECHANICAL ERROR...I did my homework, talked to guys that actually managed and flew them...the only gotcha seemed to be ice...just fly them fast 160kts+....to keep the ice off..
I later moved up into corporate jets....Ultras and Encores that I flew single pilot.....and honestly...they weren't fast enough for me...
I really do think one of the biggest limiting factors to improved aircraft designs are the lack of pilot abilities...people liking slow docile King Airs to little hot rods...that actualy get you there in a reasonable time vs some lumbering whale, banging around in the 20s through all the weather...
When they design a super sonic single pilot corporate jet, that the pilot can retract the wings back to go fast...the debutantes will really scream....
So my hat's off to the pilots that fly all the 'dangerous' planes...
Oh, yeah...positive rate....then gear up....right?? Always amazed me to see some guys throw the gear up right after the nose came up...now that's dangerous...a little time to make sure the plane is going up, never hurt anyone before putting the gear up.....
