I admit there will probably come a time when pilotless aircraft have proved themselves to be better than those with a human interface (yuk). Until then, I'll trust one of us highly trained lot anyday to take to my family home!
UCAVs on the other hand, will come - and come quickly - probably as recce/SEAD/spiking role rather than BAI/CAS/strike.
Possibly, I may be shortsighted but I am able to get some specs/contacts, rather than have my eyes lasered at all!
