Solar eclipse - 90 minutes from coast to coast

Today Moon's shadow is going to cross from Pacific to Atlantic coast of the US in 90 minutes:


It takes passenger jet 3.5 hours to fly the same distance (e.g. from San Francisco to New York)

We (in Ponte Vedra, FL) are going to see only partial ~90% solar eclipse.
San Francisco is going to get 75% of the eclipse 90 minutes ahead of us.
