The Home Office has reportedly rented an aircraft hangar and fuselage for security officials to practice forcing asylum seekers onto deportation flights to Rwanda.
The Times reported that the guards underwent special training programs to deal with “disruptive” people.
This includes individuals resorting to violence to prevent them from boarding a plane and protesters “playing death” by lying on the ground and refusing to move.

The newspaper said that security officials are also preparing for the possibility of activists holding demonstrations outside an air base in an attempt to stop flights.
It is estimated that five officers will be needed for each immigrant deported.
The Ministry of Interior did not deny this report.
A Government spokesperson said: “Since 2015, the Government has had training facilities to ensure escorts can respond professionally to the challenges of removing people who have no right to be in the UK.
“This includes practical sessions, so the escort has the skills they need to deal with different scenarios.
“As we intensify removal activity, we will continue to ensure that new attendants have the necessary training facilities.”
Overseas escorts on deportation flights must undergo the Home Office's Escort Safely (HOMES) guide course, which covers restraint techniques to use in different scenarios.
This is alongside the wider Initial Training Tribunal (ITC) on how to safely distance people.
The exercise emerged as a senior Conservative colleague doubted the stalled £290m scheme would ever get off the ground.

While Rishi Sunak prepares to do battle with the Lords over legislation Aiming to revive the planFormer Scottish Conservative leader Baroness Ruth Davidson said there were “dogs in the streets who know” the flights “will probably never happen”.
She told the BBC's The Today Podcast: “Every sovereign country should be responsible for who's coming; not everyone has the right to go to every country in the world – and I totally understand all that. But where is the balance in this, rather than… Is that from some of the language used, or from some of the complexes that people fall into?
“And this thing about putting people on planes to Rwanda. I mean there are dogs on the street who know this is probably never going to happen.
“And secondly, if it did, it would be such a small number that it wouldn't make much of a difference to the final outcome.”

Senators have long expressed concerns that the policy may violate international law.
Speaking to reporters from Hampshire on Friday, Mr Sunak said he was “determined” to get the bill through Parliament, so the scheme can be up and running as quickly as possible so we can properly resolve this issue.
The Rwanda policy is seen as central to the “Stop the Boats” pledge that Sunak bet on during his premiership.
