California, 27 marzo 2004 - Settemilasettecento chilometri all’ora, ossia sette volte la velocità del suono: è il nuovo primato di velocità per un aereo spinto da motore in atmosfera.

Lo ha ottenuto oggi un aereo sperimentale X-43 senza pilota, una via di mezzo fra un velivolo ed un razzo, come ha spiegato la Nasa, l’ente aero-spaziale statunitense.

l’aereo ipersonico è stato sganciato da un'ala di un bombardiere B-52 modificato, ha acceso un razzo ausiliario a 30.000 metri di quota, e per una decina di secondi ha volato con la spinta del proprio motore, raggiungendo il nuovo primato di velocità prima di precipitare nell’Oceano Pacifico.

«È un successo, tutto ha funzionato come previsto», annuncia la portavoce della NASA, Leslie William.
