Contrails do not necessarily evaporate quickly. There have been numerous studies into contrail physics, and it has been proved that contrails can form cirrus clouds under the right conditions. Here is a link to a scientific study done on the subject: http://www.pa.op.dlr.de/~pa1c/JAS57_464-480_2000.pdf
Thus, we cannot use their lingering as proof, since contrails do this.
About the contrails which appear to be coming from a part of the aircraft other than the engines. Do you have any photos of this? Second, if you do, how do you know that contrails always form behind the engines? The dynamics of a complex airfoil moving through a fluid are extremely complicated. There is an immense amount of turbulence aft of the trailing edge of the wing airfoil. It might be that the contrails are actually laterally translated outwards due to low pressure areas behind the wing tips. I wouldn’t jump to conclusions and say that since the contrails don’t form directly behind the engines, they aren’t contrails. Just some food for thought.
