What happened
On 1 January 2011, a Cameron O-120 hot air balloon, registered as G-BVX1, was involved in an incident near Midsomer Norton, Somerset. The event occurred at approximately 09:47 UTC.
The investigation
During the review of the investigation findings originally published in AAIB Bulletin 10/2011, a technical discrepancy was identified regarding the supplementary oxygen system used on the aircraft. The initial documentation incorrectly stated that the oxygen cylinder was supplied at a pressure of 200 psi.
Upon further verification, it was established that this was a typographical error. The investigation confirmed that the oxygen cylinder pressure was actually 200 bar.
