* A work of art that's appraised at $10,000, for example, but that's priced for sale at $5000, is not necessarily a bargain. As stated above, a retail or insurance appraisal can be many times the fair market value of a work of art. Always determine fair market value first, no matter how big a bargain the seller makes you think you're getting.
In general the aircraft must be at least 500 feet away from any person, vessel, vehicle, or structure. In congested areas the aircraft must stay 1000 feet above the highest obstacle within a 2000 foot radius of the aircraft. There are special rules for helicopters that allow them to fly closer than these general limits.
Air travel Pregnant travellers can normally travel safely by air. In the absence of medical or obstetrical complications, pregnant women can safely fly up to 36 weeks gestation. Most airlines restrict travel in late pregnancy or may require a written confirmation from a physician.
