An alert pilot remembers that the heat source is generally 50 to 60 feet [15 to 18 m] below the high point of the balloon, so it could take between 15 and 30 seconds before the craft responds to the heat from a blast of flame.
Pilot yang waspada selalu ingat bahwa sumber panas letaknya kira - kira 15 sampai 18 meter di bawah puncak balon, sehingga dibutuhkan antara 15 dan 30 detik sebelum balon bereaksi terhadap panas dari semburan api.
