Chromed stowpipe Is it necessary to have a tailpipe to be a VLJ Seeing that most such planes fly 6xx to 7xx km h speeds maximum a prop jet could have nearly the same speed and better fuel economy I mean something like the six seater executive version of the Pilatus PC 12 with an 1600shp engine instead of the current 1200hp powerplant and 5 blade airscrew could fly maybe 600 km h and with just a few dozen kilos of weight reduction it could fit the 10k lbs limit It would have huge range advatage over pure jet VLJs
