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.
Modri piloti atceras, ka deglis atrodas 15 līdz 18 metrus no balona virsotnes, tāpēc ir nepieciešamas 15 līdz 30 sekundes, pirms balons reaģē uz liesmas radīto karstumu.
