I'm a skeptic. I can do nothing but doubt your story until you provide evidence confirming what happened.
If you provide a location and date I can try to do the work for you and confirm your story via investigation (news accounts, witness statements, incident reports) and corroboration using common sense, logic and skepticism as a filter to try to validate your account. Otherwise, your claim may as well be "I saw a ghost two blocks from my home."
I do not know that you exist, where you exist, that the plane you claim crashed existed or, if it did in fact exist, that it crashed on the date or in the location you claim. The onus is on you to prove otherwise if I'm to believe your story.
