Fave Aircraft?
That's easy, Douglas DC-3.
Lots come close, but the DC-3 has it all for me, innovative, ubiquitous, beautifully photogenic, reliable, easy to fly, versatile - has been a combat aircraft too in several wars and it's built like a tank. Imitation being the sincerest form of flattery, the DC-3 was even copied practically down to the last rivet by the Russians as the Li-2.
Even though it's now 70 years old as a design, many are still flying and it is still a viable means of transport. Lots of aircraft get called flying legends, but the DC-3 really is one - legendary, and still flying on a daily basis.
