  • There's a major part left out, the reason the Barringer event was so devastating, given it's small size, was BECAUSE it was iron. Had it been a stony rubble pile, there would be nothing there today. Quite a difference. So a city-sized or 800m iron meteor would be enough to cause the deaths of half the planet by the time all damage from nuclear winter, economic (imagine a Great Depression x4 in depth and world-wide), starvation, disease, etc, is factored in.

  • 1988 circulaba por tramo de autovía N 340 desde Tarragona a Barcelona cerca del barranco de Llevant en la primera ciudad,y en dirección la ermita del Loreto aprecie la caída de un aerolito. Cayó en vertical,, cómo era pleno día aprecié su masa negra,humo negro detrás de su masa y luego humo blanco,No pude ver más al tener lomas enfrente.Posiblemente cayose al mar a la altura de Roda de Bera o así.La masa que aprecie fue como la cabeza de una cerilla.Ningun comentario en prensa.
