SIGN the GUESTBOOK. Hickam AFB passenger terminal has two overhead flat screen monitors, your sun clock and their arrival/departure. I was stranded there for two days and was in awe at the accuaracy of your site. I retrived your site now to plan communications with contacts in Japan.
4 - The ideal wind speed for hot air balloon flights - To provide the best conditions for a safe balloon flight landing the maximum surface wind speed on the day of the balloon ride must not exceed 10 miles an hour.
Hot air rises. The envelope traps a large bubble of hot air. When the air in the envelope is heated by the burner, the balloon will rise. When the air in the envelope is allowed to cool or if the hot air is vented (allowed to escape) from the top of the envelope, the balloon will descend. An altimeter (to measure altitude), a rate-of-climb meter, and an envelope temperature gauge are the only instruments used in the balloon.
