The two occupants of the ULM and three passengers of the tourist plane are said to have died.
The tourist plane had taken off from the city of Poitiers, located about 100 km from Loches.
The ULM’s flight path remains unknown at this time.
The fatal collision occurred in the air above the entrance to the small town, on the Châteauroux side.
One plane crashed into the fence of a house, while the second landed several hundred meters in an uninhabited area, according to local authorities.
No other members of the public were injured.
About fifty firefighters and thirty gendarmes were dispatched to the scene, as well as several aviation specialists.
The photos show emergency vehicles and other cars backed up on a road as a perimeter has been set up by police to keep other motorists and pedestrians away.
Nadia Seghier, secretary general of the prefecture of Indre-et-Loire, told French media that the two planes had landed at some distance from each other.
“A small ULM carrying two people and a DA40-type tourist plane carrying three people telescoped around 4.30 p.m. to 5 p.m., the first landing on the fence of a house in Loches, without causing additional victims, the second at several hundred meters in an uninhabited area, ”she told Agence France-Presse (AFP).
Investigations are said to be underway to determine the cause of the tragic accident, entrusted to the Loches gendarmerie brigade.
A little over 6,000 people live in the town of Loches, located in the Indre-et-Loire department in central France.
In August, two people were killed in an accident at the ULM in Saint-Martin-de-Londres. The man and woman, aged 60 and 55 respectively, allegedly struck a tree and caught fire at the end of a flying club strip.
