A Nimrod flight from RAF Kinloss was cancelled after delays for safety checks on the fleet over a "minor technical issue".
The Nimrod flight was rescheduled for Wednesday morning
The Nimrod was due to take off from the base, which is in mourning after the Afghanistan crash, on Tuesday morning.
The Ministry of Defence (MoD) said there was a potential issue not related to the crash. The launch was later rescheduled for Wednesday morning.
Twelve of the 14 men killed in the Nimrod crash were based at RAF Kinloss.
An MoD spokesman told the BBC Scotland news website: "We had planned a launch and put it back.
"There was considered a potential technical issue across the whole fleet not related to the crash.
"These things are not uncommon, as a matter of course they will look at the others."
The training flight was eventually cancelled for the day, the captain deciding the crew had been ready since the early hours in a "trying week" so they were stood down.
All non-essential flights from the base had been grounded on Monday as a mark of respect for the victims.
A four-man board of inquiry will investigate the cause of the crash, which is thought to have been due to a technical fault.
Chief of the Air Staff Air Chief Marshal Sir Glenn Torpy said that the Nimrod had just completed a routine air-to-air refuelling when a fire was reported on board.
He said: "We have definitely got an early report that the pilot reported a technical problem connected with fire.
"The whole recovery operation for the wreckage is ongoing at the moment and I cannot confirm at the moment whether they actually have identified the black box."
Relatives have been paying tribute, with Sgt Benjamin Knight's older brother Andy saying he had wanted to help the people of Afghanistan and "died doing what he loved".
Military and civilian personnel held a service at the base where prayers were said and a minute's silence observed.
The small Moray community is beginning the healing process, with counselling being offered to both young and old.
Moray MP Angus Robertson is urging the government to send the bodies straight to RAF Kinloss rather than RAF Brize Norton in Oxfordshire to avoid any delays.
