Andriani did not deceive himself, for, sure enough, his first attempt did not come up to expectation. The reasons for this failure were the too great quantity of air which the fire drew in, and the unsuitable character of the fuel used.
On the 25th of February, 1784, a second attempt was made. The fire was lighted under the machine, at first with dry birch-wood and afterwards with a bituminous composition, ingeniously concocted by one of the Brothers Gerli. In less than four minutes the balloon was completely inflated, and the men employed to hold it down with ropes perceived that it was on the point of rising. The aeronauts then gave the order to let go. Scarcely was the balloon let off, when it gently rose a short distance, and then flew in a horizontal direction towards a palace in the neighbourhood.
