The fact that an aircraft built in the 1960s is still in daily service tells something, surely !
There are many here who would just love to have a ride on an Il-18, and would have no concerns at all. Do take photos and post them here. As for the comment above about the Tu154, last year I made a trip, from Gatwick, to St Petersburg, Russia, one way on a 737, the return on a Tu154. Give me the 154 any time, felt a really nice, solid, comfortable, stable aircraft.
