winglets
Greetings for all!
This may be the most asked question or not! but why Boeing 777's do not have have wingtip devices? but 737s winglet program caught like a fire for NGs. I know the latest are designed with ranked but not as popular as NG's original or retrofitted 6 feet winglet. Any ideas?
PS: as the reason behind the wingtip devices is to reduce the induced drag and especially long haul flights, The aeroplane which can virtually connect two cities in the world as they say doe not have any. this itches my head!
