The IAF Sukhoi Su-30 fighter went missing near the India-China border last week.
Search and rescue teams on Tuesday found a blood stained shoe, half-burnt PAN card and a wallet of one of the two pilots of the Air Force's Sukhoi-30 fighter jet that crashed near the Assam-Arunachal Pradesh border last week, officials said.
The teams comprising the Army, the Air Force and civil administration personnel had recovered the jet's blackbox on May 28 from the crash site, located in a dense forest.
"Search operations are continuing despite bad weather conditions. However, there is still no trace of the two pilots," Army sources said.
The wreckage of the fighter jet, which went missing on May 23, was found on May 26 through aerial recce, in a thick forest around 60 km from Tezpur city.
The Sukhoi Su-30 had taken off from the Tezpur air base, around 10.30 am on a routine training mission but lost radar and radio contact with the controlling station around 11.10 am near Arunachal Pradesh's Doulasang area, adjoining China. It was part of a two-aircraft formation when it went missing.
The Air Force has called an inquiry into the crash.
Tezpur has one of the three Air Force air bases in the country that host the Sukhois.
