I flew the 125/800 for a couple of years. Its a nice hands on aircraft,and fairly easy type to do a rating on compared to the G4,which is by far more complex in most of its systems. The G4 is a true beauty on the ramp and in the sky, a roomy flt deck and unbelievable power. However,i am truly happy with my hands on the BBJ. A flight deck with loads of room,a real smooth ride,tried and tested systems of the 737 and power to get us up to 410 in no time at all.. .I'd love to have a go on a Lear though, now that looks like fun!
