Listen to this radio conversation between Pilot Clarence, Co-Pilot Roger, Navigator Victor and the ATC station.

ATC: “209 You are cleared for take off”
Clarence: “Roger”
Roger: “Huh?”
ATC: “L.A. departure frequency 123.9”
Clarence: “Roger”
Roger: “Huh?”
Victor: “Request Vector, over”
Clarence: “What?”
ATC: “Flight 209 cleared for vector 324”
Roger: “We have clearance, Clarence”
Clarence: “Roger, Roger. What is our vector, Victor?”
Victor: “LA radio clearance, over”
Clarence: “That’s Clarence Oveur. Over”
Victor: “Roger”
Roger: “Huh?”
ATC: “Roger, over”
Roger: “What? – Huh? – Who?”

LX289 arriving from FAJS obviously was to early to land on rwy 34 in LSZH and was sent into an exceptionally wide holding pattern.

To treasure the subject and issues that Aaron Swartz was fighting for, I would like to refer and remind to my mail to Richard Stallman, Lawrence Lessig and Cory Doctorow, which I wrote on 21st of January 2012.

Keynote speech about Copyleft

Here’s how one can convert latitude/longitude values from degrees to decimal format using GNU awk.

# description: convert dec values to lat/lon
# license: GPL 3.0
# input: "N010.00.21.698 E094.24.35.999"
# output: "10.006027 94.41

printf "%.7f %.7f\n", latdec, londec;
}'

usage:
echo "N010.00.21.698 E094.24.35.999" | ./awk_converter.sh
output:
10,0060272 94,4099997

… the 27th of December was quite a windy day for LSZH approach. – Especially for the poor Phenom and Falcon 2000 the landing must have been quite shakey!1!!
