Good morning, everybody! I'm the pilot of that beautiful glider.

A few points

1) I have the transponder on all the time when I'm over 10,000 feet (or in controlled airspace, or America) - which means I'm being data logged by ATC, flightradar24, etc. I fly as if I'm visible all the time.

2) I file a flight plan for any flight that might require clearances. You Americans are lucky (at least in Montana), we have Class B airways all over the place in Canada.

3) I start talking to Salt Lake well before crossing over, keeps the blood pressure down on the air defense types.

4) It is necessary to get pre-clearance to land in the USA. I have done so but the conditions prevented the trip). US customs tells me they don't want me to do so on every overflight. They would prefer to see emergencies treated as such.

Many Canadian glider pilots are also very confused by how to legally overfly the USA. Pretty simple - file flight plan, use transponder and get unique squawk code, talk to ATC, don't land out.

AWESOME FLIGHT!!!
