El Salvador Earthquake

Hello everybody, this is my first post and I decided to publish this 2 pictures because they were taken by my cousin , who is a commercial pilot who does not believe in UFOS until today I guess !! I asked him several times if he has witnessed something different on the sky all these years ( he is retiring in 2 years ) he said NO , until yesterday ! in my personal experiences I have witnessed 3 events in my life that I always tried to relate with conventional explanations, but is just not possible to relate with any known technology.

my cousin said that he was flying from Mexico to El Salvador at the moment of the earthquake, he told me that clouds had a weird formation at that moment and he took a picture with his iphone , then something appeared in the middle of the clouds very fast , he said that it was not a plane and his instruments never detected any other type of plane near them, asked the control tower and they cannot see anything on radar. (His plane was flying over the epicenter at the time of the earthquake )
