...from two flights to 8,400' and 19,800' at Aboyne, Scotland, April 1999

Early morning wave to the east of Aboyne

Deeside

Heather burning scars

Lots of bright reflections and not much else!

Cirrus showing some high-level wave?

The town of Ballater from about 8,000 feet

Wave leading edge bulging up in front of the glider

Another glider just below, into the sun

A classic medium-level lenticular cloud

Lenticular stacks in the far north-east

Two gliders, one almost invisible (ringed)

Classic wave undulations and slots

More morning wave before the next flight

Vega cockpit - going up nicely

A nice long slot

Too bright, into the sun

Nearly 18,000 feet, slots clearly evident in the wave

Snow-capped mountains beneath the wave

A huge wave bar covering Lochnagar, from 19,500 feet

The valley of the Dee seen through this large slot

There's nowhere safe to land on top of this mountain!

Meeting someone (top right), on the way down

Planning to go down through the slot on the left

12,200' on the way down, with cold feet, at 100 knots

Just about to dive through the slot on the left, and the film ran out
