took the hint
folks,
etops on 747 and 340 surely wasn't the smartest way to start a question. should have reread the post before sending it into cruel pprune forums, where only chuck yeager&son are invited to ask questions. sorry i should have done better.
do my independent research?
well i did, but was hoping to get more info from fellas who don't mind to help.
anybody who feels asking questions in this forum is the lazy way of studying, do me a favor, keep moving.
cheers
