I think that sometimes are errors and sometimes are on purpose (Who knows? they have there reasons)... There are so many posibilities because mainly
we don't know the race (or races), or even know if they exist. Imaging some irresponsable aliens passing by:
"# I just realized our camouflage is off!"
"Damn Bert! You think the boss noticed?"
"Look at those common tourist down there in the woods... Let's do this again
In a more serious tone... I think those aliens or beings, if they do exist, aren't perfect. So crashing or being spotted by a satellite are mistakes.
(Although I don't think that the "show" sightins in brazil and mexico with cool movements and tricks are mistakes...)
