Orange colored beings thats possibley from another planet

what i remember is around 1984 when i was in (Sally K) pre-k we where on our way on a field trip. There was maybe about 10 of us on the van with 2 adults.  
Into our long road trip when i noticed that we made a wrong turn down this rocky area i saw big spins of electrical wire, big rocks and a small like maybe a security both.  The driver of the van all of a sudden paniced and spinned the van around in a great speed.
As i looked out the window of the van i saw 2 but maybe could have been more.  i cant remember if they where short or tall but they where orange colored people dressed in all white suits.  Their heads where big, and it was plain as day that they where not from this planet.  
This memory pushes my intrest in the UFO phenomenon and i would really want to know what it was i saw
