Captain Garmin,
The attempt will be overhead Lethbridge Airpark at 7am this Saturday. The aerodrome itself is restricted ops at the moment due runway works. I'm not sure that it's possible to fly in, probably contact Gary.
And an extra special plea to possible non-radio aircraft that like overflying CTAF's, would you mind not doing this, there will be a Pitts & chase plane operating.
This is CASA approved event/display. Both pilots are formation rated.
