The precise regulations are given in Part 103 as referenced above, but in general, you must stay out of controlled airspace (around larger airports) unless you have permission, and you must stay below 18,000'. You may not fly over "any congested area of a city, town, or settlement" or "over any open air assembly of persons" at ANY altitude. As far as launching and landing, it's up to local laws, if any, and landowner permission.

We ask pregnant mothers and guests taking medications to consult with their physician before flying in a Hot Air Balloon.

Why airships fly is explained by the Principle of Archimedes: "Bodies submerged into a fluid receive from it a lifting force which is equal to the mass of the displaced fluid." (This is the same principle that explains why boats float on water.) The airship is filled with a lifting gas (Hydrogen, Helium, hot air or natural gas). The air in which the airship finds itself has a higher specific weight than the lifting gas.

We would recommend not flying for 1 week after treatment, this is due to the dry atmosphere inside an aeroplane. We will schedule your aftercare appointments for 1 week and 1 month after treatment and we recommend that you attend these appointments.

Yes. We do not have any specific threat to flights in the U.S. However, out of an abundance of caution, we have taken these steps as a precautionary measure. We continue to monitor intelligence sources closely and will adjust the security measures as warranted.
