fireball at night went under car on highway.

At night I was driving north on I-91 near Hartford, CT.  It was a hot night, probably in July or August.  All of a sudden a small fireball appeared to the left of the car, as if having fallen from the sky.  It landed on the road near my car and must have rolled under my car.  My friend screamed, "What the H**** was that?"  I was scared that it would ignite the gas in the tank and make the car catch fire.  That's all we saw of it, even though I looked in the rear view mirror to see where it went.  We never had any explanation of this except that maybe it was a meteorite.
Date is approximate.  One of two reports from same witness, who elects to remain anonymous.  PD
