nipva: correct, until the infamous 'demonstration arrested landing' for John Nott (?) conducted in RED wx conditions (I ask you!) when the BAK-13 cable snapped (due to co-incident chute deployment) and re-organised the rear-end of the subject F4. After which the BAK-13s were 'withdrawn' and we had to use the 2 x RHAGs only, with the concomitant massive increase in re-wind/reset times and reduced rate of recovery.
