My passenger from the 13,000 foot flight [click here to read] has sent through some photos from the flight, including the important one! Thanks Amy. Top to bottom we have:
The evidence! Altimeter plus other instruments
Still climbing, but close [middle-right hand side is Wellington, in the distance is the South Island]
Heading back to Wellington, at the Te Marua water reservoir, only about 3500 feet at this stage
I am now wondering if it is worth while getting current in the PA38-112 Tomahawk, to see if it can reach this high??! looks like the service ceiling is 13,000 feet, but that's probably with a factory new aircraft at minimum weights, not a 40-odd year old airframe with an old engine.. I'll see... I need to save some money first!
