What really happened : http://news.bbc.co.uk/2/hi/south_asia/4986586.stm
Passengers were forced to accept airline hospitality for longer than expected earlier this week when it was refused permission to land in the US.
The plane was diverted to Canada after US authorities were reported to be concerned about its mechanical flaws.
The incident is the latest in a series of setbacks for the national carrier.
On Tuesday the cash-strapped airline announced that it may suspend long-haul flights to Europe, America and parts of Asia in an effort to reduce heavy losses.
Services to New York will be cancelled and flights to Tokyo, Paris, Frankfurt, Bangkok and Singapore may be affected.
Biman's erratic passenger schedule, the poor state of its 13 dwindling and elderly aircraft, its bloated staff numbers and its failure to pay fuel bills have all given the impression that it has hit severe turbulence.
Analysts say that years of rampant corruption and incompetent management have led to fears that the airline's future is by no means secure.
"We are suffering a loss of $80,000 on each flight to New York because of operating old DC-10 aircraft," says Aviation Minister Fakhrul Islam Alamgir.
"We urgently need to replace the fleet, but we don't have the funds to do so."
The minister is no doubt well aware that there is barely a single case of aircraft-leasing by Biman in recent years that has not been accompanied by allegations of corruption - with government appointed middlemen usually named as the beneficiaries.
The airline's woes have been pinned by many observers on the government's reluctance to relinquish control of Biman and allow it to stand on its own feet.
'Rolling in wealth'
The loss-making flight from Dhaka to the US was only reported to have survived in recent years because Prime Minister Khaleda Zia insisted in 2004 that it be kept going in the interests of the country's "national prestige".
"Biman has always remained an appendage of the Civil Aviation ministry," says an editorial in the Bangladesh newspaper, The News Today, "with too many people competing to get their fingers in the pie.
"The management structure has always been mediocre, with former Air Force personnel monopolising the chief executive's post.
"It is almost impossible to find a single senior Biman employee, from cabin crew to middle management, who is not rolling in wealth."
The price of these failures is clear to see: hundreds of passengers suffering daily delays - usually between six to 24 hours - and many requiring food and accommodation.
One report estimated that Biman pays every passenger it transports an average of $20 in compensation for delays.
The government insists it is working to make Biman more efficient and claw back loses which approached $42m last year.
It says that it is trying to find a "strategic partner" to improve the airline's fortunes.
But it said the same thing five years ago - and true to form - more delays are expected.
