Recreating ‘Flight of the Double Sunrise


As we announced in year 2012, ALK-VA has operated 70th Anniversary flight of 'Flight of the Double Sunrise' on 29th June 2013.


70th Anniversary Flight


ALK-VA pilots completed Catalina route proving flights along the west coast of Australia.

Flight details are highlighted below.

This test flight was carried out in Sri Lanka after SLAF fully refurbished & handed over the Catalina to ALK-VA. Water landing carried out at Koggala Air Base. All airframe modifications were accomplished before the last year's flight. Initial aircraft performances calibration & engine fine adjustments were practiced. On completion of testing aircraft was shipped to Perth. Flight duration 02:40hrs.

Bunbury Airport (IATA: BUY, ICAO: YBUN) is an airport servicing the Western Australian city of Bunbury. Bunbury Airport is located 8 km (5.0 mi) south-west of the city centre and is the only airport serving the city. The airport is used largely as a facility for general and recreational flight training. First test flight in Australia. Practiced navigation using only the compass and manual drift calculations. Challenging weather conditions for VFR flight with fog patches. Flight duration 01:00hr.


Fog & low clouds... ideal for VFR flying!


Albany Airport (IATA: ALH, ICAO: YABA) is an airport serving in Albany, Western Australia. It is located 6 nautical miles (11 km; 6.9 mi) northwest of Albany just off Albany Highway and operated by the City of Albany. Also known as Harry Riggs Albany Regional Airport, it is the largest airport in the Great Southern Region. Flight completed with isolated airfield landings at Busselton [YBLN] and Manjimup [YMJN]. Most challenging aspect was fine tuning of engine parameters under low temperature conditions. Flight duration 01:42hrs.

Rottnest Island Airport (IATA: RTS, ICAO: YRTI) is a small airport for light aircraft, situated about 800 m (2,600 ft) from the main settlement at Thomson Bay, Rottnest Island and 10 nautical miles (19 km; 12 mi) northwest of Fremantle. Catalina's Long cross-country flight ended with an island landing. Flight duration 02:42hrs.

Geraldton Airport (IATA: GET, ICAO: YGEL) is an airport located 6 nautical miles (11 km; 6.9 mi) east of Geraldton, Western Australia, along the Geraldton – Mount Magnet Road. Taken a long over water route. Encountered rain and low clouds. Flight duration 02:16hrs.

Rain & low clouds challenged VFR flying conditions

Rain continues at YGEL


Carnarvon Airport (IATA: CVQ, ICAO: YCAR) is an airport at Carnarvon, Western Australia. Encountered rain and low clouds along the route. Flight duration 02:24hrs.

En-route to YCAR

Runway 04, crosswind landing at YCAR


Dress rehearsal for the next week's real thing. Flight was planned for extended over water navigation using map, ruler, compass & clock. Approached VRTI via Perth VOR in total darkness. Nearly full moon helped with some ground feature identification. VHF Omni Receiver readings found unreliable. Further testing will be carried out in the coming days. Fuel usage found within estimated values. Flight duration 06:38hrs.

VHF Omni Receiver calibration completed. Carried out two runway landings at YRTI & two water landings at Swan river. Port engine overheated due to repeated full power takeoffs. Allowed engine to cool while idling on Swan river. Final fuel usage estimate shows 92-94% of fuel load requirement for the next week flight. Flight duration 0:42hrs.

End of the mission!




An year has gone so fast since our last flight, east bound from Koggala to Swan river. Due to the encouragement and comments we received then, we planned to do the return west bound flight also. It is even more special this time, because the 70th anniversary of the original flight.

Flight preparations were on schedule, but as usual fine tuning of Catalina controls was essential and time consuming. Using last year fuel consumption calculations and as per the prevailing wind conditions we decided to reduce fuel load. Results were better than expected. This was mainly due good tail wind conditions encountered most of the time.

As you can see in the Flight Log Book entries given above, flight experienced its own set of events, exhilarating as well as near disasters. We witnessed some of the most beautiful sky views that we have ever encountered. Fortunately we had all the time in the world to enjoy those unforgettable scenery. When Koggala coast appeared on the horizon we could imagine how those airmen who flew these flights under real world conditions must have felt. Feeling was such a huge relief, very much different than when we saw Australian coast last year, as we had to fly many more hours then, along the coast.

Longest non-stop flight that we have experienced in real life is just over 16 hours. Comparing the comforts available for both pilots and passengers now, it is nearly incomprehensible to understand the conditions of those historical flights. Catalina's deep engine noise along with non stop cabin vibrations alone can make the flight unbearable within few hours. Withstanding it for 30 hours... that is ultimate airmanship. We at ALK-VA salute once again all those flyers.

Another record breaking flight... someday in the future. But that will not be between Koggala & Swan river.

Actual Airplane Maintenance Log Book Entries

You might be a freight dog if...



“Because civil aircraft are designed to fly safely for unlimited time provided defects are detected and repaired, safety becomes a matter of detection and repair rather than one of aircraft structure failure. In an ideal system, all defects which could affect flight safety will have been predicted in advance, located positively before they become dangerous, and eliminated by effective repair. In one sense, we have changed the safety system from one of physical defects in aircraft into one of errors in complex human-centered systems.”
