Recently added to Saab's website is this picture of Swiss air force pilots perform test flights with Saab Gripen E/F test aircraft. On 30 November last year the Federal Council selected Gripen E/F as the preferred candidate to replace the Swiss service's ageing fleet of Northrop F-5E/F Tigers. This example is piloted by Lt Col Fabio Antognini, together with Richard Ljungberg Saab chief test pilot.

To celebrate 30 years of flights to London Heathrow, American Airlines has released this tremendous, nay, glorious image of members of staff dating from 1988. I think it's probably the hair - just the wrong side of boufant - that does it for us. As to whether the jet is still in service, well, it's American, so who knows...

Picture: Alaska Airlines

Alaska's waters are rich in salmon, a delicacy that is regularly flown to the contiguous forty-eight and beyond on Alaska Airlines aircraft. The Salmon-Thirty-Salmon livery, that highlights the carrier's connection with its home state, had been pulled out a while ago, but the Alaskan airline has announced it is reintroducing it later this year. A reason for spotters to rejoice!

"Never before have humans and aircraft flown this close in formation. It is the first performance of its kind in the world," said a proud Paul Steiner, leader of the Red Bull Skydive Team.
