Qantas had a couple of serious incidents on 707s in the sixties. One that I witnessed at Paya Lebar, was a 707 landing hard on 02 and subsequently going around, barely missing the coconut trees at the end of 02. Apparently the landing was carried out by the PF under training in the right hand seat. RW02 had a dip at the approach end, the aircraft hit the runway nosewheel first, displacing the nosegear rearwards and thereby splitting the fuselage in the L41 area. A repair team flew out from Sydney and they patched up the aircraft for an unpressurised ferry flight back to Sydney. Luckily, there were no injuries to pax or crew. The other incident was on a 707 night flight, eastbound over India when the Capt's AH toppled. Capt. disconnected the A/P and followed the toppling AH. Aircraft went into steep left bank before recovery. As far as I remember, neither incident was publicised at the time.
