Debris was found and identified as AF447 within a day or so. The Brazilian Navy pulled out some bodies and recovered more wreckage within 5 days (check it out). But then, BEA took a long time to recover the black boxes because of the physical difficulties - but they had found the plane almost straight away because planes usually leave a track as the AIM is to be found - unlike in this case?
AF447 was much easier because they authorities were able to calculate the general area where AF447 had ditched and as a result they were able to find some debris.
By early afternoon on 1 June, officials with Air France and the French government had already presumed that the aircraft had been lost with no survivors. An Air France spokesperson told L'Express that there was "no hope for survivors",[62][63][64] and French President Nicolas Sarkozy told relatives of the passengers that there was only a minimal chance that anyone survived.[65] On 2 June at 15:20 (UTC), a Brazilian Air Force Embraer R-99A spotted wreckage and signs of oil, possibly jet fuel, strewn along a 5 km (3 mi) band 650 km (400 mi) north-east of Fernando de Noronha Island, near the Saint Peter and Saint Paul Archipelago. The sighted wreckage included an aircraft seat, an orange buoy, a barrel, and "white pieces and electrical conductors".[66][67] Later that day, after meeting with relatives of the Brazilians on the aircraft, Brazilian Defence Minister Nelson Jobim announced that the Air Force believed the wreckage was from Flight 447.[68][69] Brazilian vice-president José Alencar (acting as president since Luiz Inácio Lula da Silva was out of the country) declared three days of official mourning.[69][70]
Even with that in mind, it took them 2 years to actually find the wreckage and retrieve the black box.

Any comparison from my part was to outline the abnormal and unusual difficulties associated with MH370 since it had diverted from its course and because Transponders, ACARS (remarkably) and ADS-B were all disabled which was not the case for AF447.
It is also to highlight the fact that due to the massive physical challenges associated with MH370, it too may take 2 years if not more. And yes, we have been told that the search for MH370 will not stop. Discussions already in process not to mention massive political influence from China towards Australia to not stop any search efforts.
On 5 June 2009, the French nuclear submarine Émeraude was dispatched to the crash zone, arriving in the area on the 10th. Its mission was to assist in the search for the missing flight recorders or "black-boxes" which might be located at great depth.[96] The submarine would use its sonar to listen for the ultrasonic signal emitted by the black boxes' "pingers",[97] covering 13 sq mi (34 km2) a day. The Émeraude was to work with the mini-sub Nautile, which can descend to the ocean floor. The French submarines would be aided by two U.S. underwater audio devices capable of picking up signals at a depth of 20,000 ft (6,100 m).[98]
Following the end of the search for bodies, the search continued for the flight data recorder and the cockpit voice recorder, the so-called "black boxes". French Bureau d'Enquetes et d'Analyses (BEA) chief Paul-Louis Arslanian said that he was not optimistic about finding them since they might have been under as much as 3,000 m (9,800 ft) of water and the terrain under this portion of the ocean was very rugged.[99] Investigators were hoping to find the aircraft's lower aft section, since that was where the recorders were located.[100] Although France had never recovered a flight recorder from such depths,[99] there was precedent for such an operation: in 1988, an independent contractor recovered the cockpit voice recorder of South African Airways Flight 295 from a depth of 4,900 m (16,100 ft) in a search area of between 80 and 250 square nautical miles (270 and 860 km2).[101][102] The Air France flight recorders were fitted with water-activated acoustic underwater locator beacons or "pingers", which should have remained active for at least 30 days, giving searchers that much time to locate the origin of the signals.[103]
France requested two "towed pinger locator hydrophones" from the United States Navy to help find the aircraft.[71] The French nuclear submarine and two French-contracted ships (the Fairmount Expedition and the Fairmount Glacier, towing the U.S. Navy listening devices) trawled a search area with a radius of 80 kilometres (50 mi), centred on the airplane's last known position.[104][105] By mid July, recovery of the black boxes had still not been announced. The finite beacon battery life meant that, as the time since the crash elapsed, the likelihood of location diminished.[106] In late July, the search for the black boxes entered its second phase, with a French research vessel resuming the search using a towed sonar array.[107] The second phase of the search ended on 20 August without finding wreckage within a 75 km (47 mi) radius of the last position, as reported at 02:10.[108]
The third phase of the search for the recorders lasted from 2 April until 24 May 2010,[109][110][111] and was conducted by two ships, the Anne Candies and the Seabed Worker. The Anne Candies towed a U.S. Navy sonar array, while the Seabed Worker operated three robot submarines AUV ABYSS (a REMUS AUV type).[109][112][113][114] Air France and Airbus jointly funded the third phase of the search.[115][116] The search covered an area of 6,300 square kilometres (2,400 sq mi), mostly to the north and north-west of the aircraft's last known position.[109][113][117] The search area had been drawn up by oceanographers from France, Russia, Britain and the United States combining data on the location of floating bodies and wreckage, and currents in the mid-Atlantic in the days immediately after the crash.[118][118][119] A smaller area to the south-west was also searched, based on a re-analysis of sonar recordings made by Émeraude the previous year.[120][121] The third phase of the search ended on 24 May 2010 without any success, though the BEA says that the search 'nearly' covered the whole area drawn up by investigators.[122]
