Re Post 39 captain dart thanks for thr clarification about the B36 and reactors, amazing what peopel would try in the 50s. Even the B36 itself with its ten engines split between prop and pure jet power almost qualifies but I think there were other hybrid engine aircraft (not counting rocket take offs and the like)
A fantastic amazing machine though even if pretty useless by the time it entered service, single wheel main gear ona plane that size awesome.
While writing this another contender comes to mind, take off only boost engines a la Trident 3 , any other airliners ever enter service with sucha configuration?
A nice interestign thread and yes as someone pointed out it is abit harsh to blame UK manufacturers when they were only allowed to build what was specified leading to such disasters as Tudors, Brabazons etc. More fun to be aircraft afficiando in tho e days though when you consider that a trip to LHR might see ten A320s in succesion landing
