Hans-Rudolf Wöhrl, the guy behind Intro (and founder of NFD in the 1970s - later merged with RFG to become Eurowings and Germanwings and later sold to Lufthansa) is an interesting chap. Only very recently he quit pilots.de, a (much smaller) German version of PPRUNE where he every once in a while openly engaged in discussions with members (mostly pilots who prefered to remain anonymous in contrast to him) - despite getting a lot of flak for his work at NFD, dba, LTU, FlyNext and Intersky from pilots who sufferend from his restructuring work.
As you guys will know, his latest investment is Intersky, the small Austrian regional airline operating with Q300 and ATR72-600s. Although this project is mainly run by his partner Peter Oncken. Ever since his NFD days, Wöhrl is close to ATR, by the way....
