Is this a spelling due to a language reform ? I am not seeing it here https://en.wiktionary.org/wiki/Appendix:French_spelling_reforms_of_1990

Both the conjugation tools for WordReference and Reverso only list  posséderait as a spelling.

Thanks. Paul.

It seems the speaker is saying "l'impact de gigantesque."  I understand that a "de" here would be incorrect, but that is what I hear.  I presume this is because she is actually emphasizing the end of the word as in "l'impACT gigantesque."  Nevertheless, the emphasis on the end of the word seems over done.  

Later, it sounds as if she is saying "cette décision était facile."  I understand, too, that this would be incorrect grammatically, but nevertheless it is almost impossible for me to here clearly "ait été."  

Perhaps the lesson here is that one should not go by what one thinks one hears, but figure out what would be grammatically correct.  I guess that is probably what we do when listening to English.  We "sort of" listen but actually are just following the flow of the idea being transmitted and fill in the precise details only as needed.  

Is this tense more commonly used in French than in English? I hardly ever speak like this in English and I find it to be a strange tense to learn since it doesn't seem likely that we learners will be reminiscing in French. That seems to be it's only use.

I understand that the choice of verb has to do with how fast you are running.  As a former runner, I don't see a great difference between trotting and jogging.  My dictionary gave trottiner as a possibility for jog.  Should it have been acceptable? 

In the sentence,"Selon les témoins que j'ai interviewés, et aussi incroyable que cela paraisse, un hélicoptère se serait posé dans la cour de promenade de la prison et La Fuite serait monté à bord avant qu'il ne redécolle, tout ça en quelques minutes à peine !", I don't understand the use of the present tense of redécoller when we are discussing something that happened in the past in particular when it is preceded by two past perfect verbs, se poser and monter.  Also, why is ne inserted before redécoller?
