By mid '64 Tengah Javs were a mix, including the redeployed 64 Sqn FAW9R where the inner pylons were long range tanks, only 1 Firestreak per side. Extra fuel came in useful for escorting Beveley/Hastings supply drops and charging around the Sarawak/Indonesian border at low level.
In passing, the erks incredulity at the crew/official story was balanced by disbelief that AI17 would get the beast in firing range, and that a Firestreak would actually hit anything.
