I had a beer with a B-1 Lancer pilot who was here on exercises many years ago. He said that on low level flight infiltration exercises, his normal method to go over ridge lines and small hills is to pull the aircraft gently up, roll it inverted and pull back while cresting the ridge, then roll upright once over.

He said he is experienced enough to maintain 1.0 to 1.5G throughout the manoeuvre, and the most of the time, the weapons guys in the back of the plane who are usually 'heads down' and don't have big windows to look out of, don't even realise they were inverted for 10 to 15 seconds.

He said he has a standing wager with them when they land, and if the back seaters can accurately tell him how many ridgelines they crested inverted correctly, he buys them a beer. He told me he hardly ever has to buy.
