Footage of two 21 July bombing suspects as they surrendered to police has been shown to jurors.
Muktar Ibrahim, 29, and Ramzi Mohammed, 25, were filmed emerging naked from the waist up onto the balcony of a flat in west London.
Woolwich Crown Court was told police blew off the property's front door and hurled CS gas inside before the pair came out in their underpants.
All six defendants deny charges of conspiracy to murder.
The four minutes of footage was taken during the two-and-a-half hour siege at Mr Mohammed's Delgarno Gardens flat on the morning of 29 July 2005.
Firearms officers in helmets and flak jackets could be seen along the balcony as smoke billowed out of the property, before the pair emerged with their hands raised above their heads.
The jury was told by one officer that the men were ordered to strip to their underwear in case they were concealing explosives in their clothes.
Firearms officers were sent to the flat after receiving intelligence, the court heard.
The door was blown off and gas canisters were thrown into the front of the building through the doors and window. Shortly afterwards, gas was thrown into the back of the flat.
Eventually, alleged Number 26 bus bomber Mr Ibrahim emerged onto the balcony, followed by Mr Mohammed, the alleged Oval bomber. Both were later arrested.
The firearms commander at the scene, who can only be identified as Whisky Alpha, told the jury that officers tried to negotiate with the two men, but they received no response.
He said another officer, referred to as Purple Four, asked Mr Ibrahim if there was anything inside the flat that could hurt him and his colleagues.
'On your mind'
Whisky Alpha said Mr Ibrahim replied: "What, like explosives?"
Purple Four said that was what he meant. Mr Ibrahim responded: "No, nothing like that'."
During cross-examination, George Carter-Stephenson QC, for Mr Ibrahim, asked Whisky Alpha whether anyone heard one of the men say: "Why are you shooting at my flat?"
The officer replied: "I never heard anyone say anything."
Mr Carter-Stephenson continued, referring to the death of Jean Charles de Menezes: "This was a number of days after a Brazilian had been shot at Stockwell Tube station.
"No doubt that was something that was on your mind at that time?"
The officer said: "Of course, my concerns were for the public, for my officers, with the balcony."
The court also heard from Detective Constable Liam McCauley, who arrested Mr Ibrahim at Delgarno Gardens.
The officer said that as they were in a police car, Mr Ibrahim told him: "Listen, I've seen my photo and I was on the bus, but I didn't do anything, I was just on the bus."
He said that Mr Ibrahim went on: "I'm a Muslim, I can't tell lies.
"OK I did do the bus, but I had nothing to do with 7/7."
Six men are accused of plotting to carry out a series of explosions on the London transport system using home-made hydrogen peroxide and chapatti flour rucksack devices.
They are Yassin Omar, 26, of New Southgate, north London; Hussein Osman, 28, formally of no fixed address; Mr Ibrahim, 29, of Stoke Newington, north London; Manfo Kwaku Asiedu, 33, of no fixed address; Mr Mohammed, 25, of North Kensington, west London; and Adel Yahya, 24, of High Road, Tottenham, north London.
The case was adjourned until Thursday.
