I planned (theoretically still do) to draw all post-war European airliners and transports, particularly Britannia as a sort of counterpart to Il-18, but considering how long is my to-do list even without it, and how slow things are progressing since I moved to UK, I'd rather not make any promises that could endanger You for a
really long waiting. :/
On the other hand, Hood has made some Trident-derivatives for Project Cancelled thread, so maybe He'd be willing to draw the original Tridents too?
