ph...... Point taken, with many modern aircraft it is possible to disguise their real age fairly well, the Jet2 fleet being a case in point. Joe public would be hard pressed to tell the difference between a 25 year old 737 and a four year old one. It was not the case back in the 60s and 70s when props were being phased out and jets being brought in. Think most punters could tell the difference between a DC6 and a Comet, par example !!!!
