Israeli media reported on Sunday that the Israeli air force has started practicing rapid refueling, the type of which would only be used in a sustained aerial attack on a distant enemy.
The process involves Israeli warplanes sent on raids thousands of miles away returning to Israel, landing and refueling without shutting off their engines in order to get back in the air as fast as possible. Naturally, rapid refueling of this type is very risky, since the fuel is being pumped not far from the jet's engines.
Revelation that Israel is doing this kind of training came just a day after the New York Times reported that Iran had moved nearly its entire uranium stockpile to a vulnerable above-ground facility.
Iran announced earlier in the month that it would enrich its uranium to 20%, a process that requires moving it to a less secure enrichment facility. The uranium had previously been stored in a deep and heavy fortified underground facility.
